Netscape does not save Address Book entries after restarting
This happens because incorrect settings are in the registry telling it how to display this information.
HKEY_CURRENT_USER\Software\Netscape\Address Book\File Location="[the path to the address book]"
HKEY_CURRENT_USER\Software\Netscape\Address Book\StartMenuWith=Entire Listing
This same fix is applicable to the bookmark file.
If these keys are missing, it's ok to create them.

This is where all the url's are kept. Since there's like 25 of them It would take a long time to delete them all individually,
so if the customer wants to remove everything, kill the entire folder and immediately reboot (or it wont take effect).

Internet Explorer Title Bar (Provided by message)
Open the following keys one at a time and edit each one individually
HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main
then this key:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main

At each location, double-click the "Window Title" item on RegEdit's right pane. Edit the "Value data" field
to show the text your prefer. If you delete everything in the field, you should get Internet Explorer's original title
bar text, which is "Microsoft Internet Explorer."
(Note: You may not find a modified Window Title item in both Registry locations.)
If you didn't find the a "Window Title" item in either Registry location, you can add one in the
HKEY_LOCAL_MACHINE section. Click once on the Main folder to select it. Then right-click the white
background anywhere on the right pane, and choose New > String Value. Name the new string value icon
"Window Title" and press Enter. Now double-click it and type the text you'd like to appear in Internet Explorer's
Title bar. This also works in IE versions, IE 4.0 and above.

NOTE: In Windows NT, the value should be type REG_SZ instead of String.
HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main\Window Title

Outlook Express

HKEY_CURRENT_USER\Identities\{Unique-User-ID}\Software\Microsoft\Outlook Express\5.0

Where you see {Unique-User-ID} above, you should instead find a user ID number that looks something like this:

{8A067580-AFEF-11D3-BEFE-9A435B3F4031}

Two things complicate matters at this point:
1. You can control the OE 5.0 title bar text separately for each OE 5.0 Identity.
2. Each OE 5.0 Identity gets its own unique user ID number. What's more, no two Windows installations
have the same user ID numbers (theoretically). If you have multiple OE identities configured, you'll find
multiple user ID entries. If you've never created a new OE Identity, then you'll find just one.

With the \5.0 key selected on the left pane of RegEdit, look for the "WindowTitle" entry on the right pane,
and double-click it to change your title-bar text. If you don't find the WindowTitle entry, right-click the left
pane's background, and choose New > String Value. Name the new icon "WindowTitle" (without the character
space between the two words used on the corresponding icon for Internet Explorer). Press Enter, then double-click
it and type the new title-bar text. The default is "Outlook Express." If you have multiple user IDs, repeat for each ID.

Internet Explorer Remains in Offline Mode
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\ Internet Settings\GlobalUserOffline=0
This has a habit of happening repeatedly, so the customer will probably have to do it frequently. It might be a good
idea to export this key after the hack into the my documents folder so the customer can double click on it any other
time it happens instead of wasting your call time later on.

How to backup and/or restore the registry in Win 95/98
The data in the Windows 95/98 Registry is actually stored in two files in the Windows directory.
These files are named system.dat and user.dat. They are marked as hidden, system, and read-only.

To Back Up The Registry:
Verify that the Windows 95 startup disk is within easy reach.
Restart the computer in MS-DOS mode, then change directories to the Windows directory.
Type the following (pressing the Enter key after each line):
attrib user.dat -h -s -r
attrib system.dat -h -s -r
Insert a blank floppy disk and type the following (pressing the Enter key after each line):
copy user.dat a:
copy system.dat a:
Type the following to return the files to their usual attributes (press the Enter key after each line):
attrib user.dat +h +s +r
attrib system.dat +h +s +r
Type Exit to return to Windows.

Restoring The Registry from a saved backup:
If the customer ever has to restore the old registry files due to a corrupted registry ,
reboot in MS-DOS mode.
WARNING: The procedure below will overwrite the existing registry .
Go to the Windows directory and type the following (pressing the Enter key after each line):
attrib user.dat -h -s -r
attrib system.dat -h -s -r
Copy these files from the floppy disk the customer used above.
To do so, type the following (pressing the Enter key after each line):
copy a:\user.dat
copy a:\system.dat
Type the following (pressing the Enter key after each line:
attrib user.dat +h +s +r
attrib system.dat +h +s +r
Type Exit.

To restore the registry to its state when you last successfully started Microsoft Windows 95/98:
Restart the computer.
When you see the "Starting Windows 95" message, press the F8 key,
then choose Safe mode command prompt only from the Startup menu.
Type the following command to move to the Windows folder
cd \windows
Type the following lines, pressing ENTER after each line:
attrib -s -h -r system.dat
ren system.dat system.bad
Restart your computer. Windows 95 uses the System.da0 file when it cannot find the
System.dat file. If this file works, Windows 95 renames it to System.dat.

To restore the registry to a date prior to the last successful start:
Restart the computer.
When you see the "Starting Windows 95" message, press the F8 key,
then choose Safe mode command prompt only from the Startup menu.
Type the following command to move to the Windows folder
cd \windows
Type in scanreg/restore
Select the date you would like to restore to. You will need to reinstall any programs
you installed after the selected date.

TCP/IP CP Reported Error 2: Error File Not Found in NT 4.0
This problem may be caused by an invalid network adapter entry in the registry .
Run Registry Editor (Regedt32.exe) and delete the following keys in the registry :
Registry Hive A: HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\ NetworkCards\"number"
Registry Hive B: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\Root\Legacy_"adapter name"
Registry Hive C: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\"adapter name"
Registry Hive D: HKEY_LOCAL_MACHINE\SOFTWARE\"adapter name"

NOTE: In most cases successfully removing the phantom adapter will solve the RAS
connection issue if there are no other problems. It may however, be necessary to remove
and reinstall RAS, as well as any other installed adapters, and any installed protocols if
removing the phantom adapter alone does not resolve the RAS connection issue.

Error 501 Invalid Domain Name
This problem occurs frequently when customers have used the Internet Setup Wizard to create their account.
Since they have to put in their user name as ELN/user, Microsoft lists that as the user in the registry.
The reg hack is:
H_KEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\Hostname=username.

Unable to open Outlook Express 5.0
This error can occur if there is invalid or corrupt information in the "identities" registry key after you have
created/reconfigured an identity. This error may also sometimes occur after having upgraded from
Outlook Express 4.0 to 5.x
HKEY_CURRENT_USER\Identities
Delete the identities folder and then run the repair tool on Microsoft Internet Explorer 5 and Internet Tools.

Invalid Location Information
This problem is caused by the Total Access software having problems reading the registry entries for locations
(otherwise known as dialing properties). This fix also works if the customer has weird numbers showing up when
they dial, but you can't seem to find them entered into the properties of the connectoid, or in the dialing properties.
H_KEY_LOCAL_MACHINE\Software\Microsoft\Windows|CurrentVersion\Telephony
(Delete all location folders under telephony.) After exiting Regedit, create new dialing properties.

The Registry is a storehouse for configuration values and settings that are used to determine how Windows
95/98/NT/2K/Me and Windows applications operate. Of course, for the Registry to serve its full purpose, software
developers must use it to store their program parameters. The Registry also keeps track of a list of hardware and
hardware configurations that the Windows 98 setup and hardware-detection routines have discovered. If you
change your hardware configuration, the Registry is updated. The keys in the Registry are similar to the bracketed
headings in the Win.ini or System.ini files. Registry keys, unlike ini file headings, can and do contain subkeys.
While only text strings are allowed in ini files, values in the Registry can consist of executable code.
The Registry is a database divided into six main branches. Each branch is a handle to a different set of key values.

HKEY_CLASSES_ROOT
This key points to the HKEY_LOCAL_MACHINE\Software\Classes registry key, which describes certain software
settings. This key displays essential information about OLE and association mappings to support drag-and-drop
operations, Windows shortcuts (which are OLE links), and core aspects of the Windows user interface.

HKEY_CURRENT_USER
This key contains user-specific settings that are built from information in the HKEY_USERS key during the logon process.

HKEY_LOCAL_MACHINE
This key contains computer-specific information about the type of hardware installed and software settings.
This information is used for all users who log on to the computer. This key has several subkeys.

HKEY_USERS
This key contains information (generic and user-specific) about all the users who log on to the computer. The generic
settings are available to all users who log on to the computer. The information is made up of default settings for
programs, desktop configurations, and so on. This key contains subkeys for each user that logs on to the computer.

HKEY_CURRENT_CONFIG
This key handles Plug and Play and contains information about the current configuration of a multiple hardware
configuration computer (for example, settings for a docking station). This key is a pointer to one of the configuration
keys of the HKEY_LOCAL_MACHINE\Config key; the configuration key (000x for example, 0001) that contains
information about the current configuration of hardware attached to the computer.

HKEY_DYN_DATA
Dynamic data (data stored in RAM on the computer) is contained in this key. This information may change as
devices are added or removed from the computer. The information for each device includes the related hardware
key and the device's current status, including problems. Device Manager uses this data to show the current
hardware configuration, and this data is used to constantly update System Monitor.
