Applications Compatibility Scripts for Windows NT Server, Terminal

Server Edition

A third method is to contact the application vendor. They may be able to identify a

method of updating the pathname in question.

Once you have found the location of the path that needs to be changed, what

should you change it to? If the path is stored in HKEY_LOCAL_MACHINE, a special

technique is used.

When a user logs on, a script (UsrLogon.cmd) will be run that maps

a drive letter to their home directory using the “subst” command.

For example, Z:\ will map to \\server\users\fredf for Fred Flounder

and to \\server\users\barneyb for Barney Baitfish.

With this technique, you can specify what appears to be a shared path, such as

Z:\mail\mailbox.dat. Yet, the drive mapping causes each user to get a unique copy

of the file in their home directory.

Some per-user files are automatically generated by the application. A mailbox

would be an example of this type of file. Other per-user files, such as document

templates, must be provided for the user. That is, you must copy the standard files

into the user’s home directory. If you specified the path as a subdirectory of the

user’s home directory, you may need to create the subdirectory too.

Per-user tasks like this can be performed in a script that is run during logon. The

script can check the user’s home directory to determine if the files or directories in

question already exist. If not, it can copy them from a “master” copy. Using a script

allows you update current users with a new application as well as automatically set

up new users you may add later.

Files Missing when normal user logs in:

When a user runs the application, it can’t find certain files that are located in or

below %systemroot%. However, if an administrator runs the application, it finds the

files.

Resolution:

Applications that use the GetWindowsDirectory() function to determine

%systemroot% benefit from an automatic remapping. For users, the function

returns the “windows” subdirectory of their home directory. Administrators, on the

other hand, get the actual %systemroot% directory.

Normally, this is useful. It automatically converts a shared file into a per-user file.

However, if the shared file is expected to exist, then it won’t be found under the

user’s home directory. This can be corrected by using a logon script to copy the file

if it doesn’t already exist.

As an alternative, an application compatibility flag exists that can disable this

automatic remapping. This is appropriate if the files under %systemroot% are only

being used for read access. For more information about these flags, refer to the

Application Compatibility Flags section of this Paper (p.12), …
