Environment

ITMS 8.x

Cause

The C:\Program Files directory and subdirectories on the the SMP server had been compressed.

In another instance of this issue a separate Task Server had run out of disk space on the agent install directory.

Resolution

On the SMP server:

1. Uncompress the C:\Program Files directory and subdirectories.  
2. Run an IIS reset from the command prompt.
3. If space is low or out of free space then add space to the server before doing the  IIS reset.
