JSI Tip 10575. When you attempt to start the WSUSAdmin application you receive 'Server Error in /WSUSAdmin Application, There is not enough space on the disk'?

When you attempt to start the WSUS (Windows Server Update Services) WSUSAdmin Web application, you receive:

Server Error in '/WSUSAdmin' Application
There is not enough space on the disk
Description: An unhandled exception occurred during the execution of the current web request.

Exception Details:
System.IO.IOException: There is not enough space on the disk.
The stack tracker had the following line in it [HttpException (0x80004005):
Failed to create temporary files directory 'C:WINNTMicrosoft.NETFrameworkv1.1.4322Temporary ASP.NET Fileswsusadminebf3efo7

This behavior occurs because you have disk quotas installed on the WSUS server and the NT AUTHORITYNETWORK SERVICE account has a a quota limit.

To resolve this issue, remove the quota limit from the NT AUTHORITYNETWORK SERVICE account:

1. Using Windows Explorer, right-click the volume that has disk quotas configured and press Properties.

2. Select the Quota tab.

3. Press the Quota Entries button.

4. Double-click the NT AUTHORITYNETWORK SERVICE account.

5. Select Do not limit disk usage and press OK.

6. Close the quota dialog.
