Windows Roaming Profiles

Roaming profiles try to ensure that your Windows environment is the same on each computer you log into. The profile consists of several directories including My Documents, Desktop, and Application Data. The profiles are stored on the file server as a subdirectory of your Unix home directory and downloaded each time you log into a PC.

While roaming profiles are generally useful in a multi-user environment, there are some problems associated with them. Data is only written back to the server at logout. This means that your data is not being backed up until you log out of Windows. If your local hard disk crashes, you are in danger of losing data.

Copying the profile from the server at login (and to the server at logout) can take several minutes for large profiles. Sometimes this process dies in the middle and your profile is left in an inconsistent state where the locally cached copy does not match the copy on the server. In these cases, Windows may choose to only work from the cached copy, meaning that your data will not be written to the server until the original problem is resolved.

Recent Changes

The My Documents, Application Data, Desktop, and Recent directories are now written immediately to a new subdirectory in your home directory called .windows rather than the previous only at logout scenario. This has the benefit of speeding up the login and logout process a great deal.

Potential Problems

As a result of these changes, those four directories are no longer located under C:\Documents and Settings\username but instead can be found in Z:\.windows. We have noticed that certain applications do not automatically pick up on this change. Two of them are Thunderbird and Netscape 7.x. If you have been using either of these applications in the past, you should take the following steps before attempting to open them again:

Two other applications require modifying the registry. These are Exceed and Corel Word Perfect. If you had been using either of these, you will need to make the following changes:
