-Verified ISA Firewall rule to ensure port 8530 and 8531 are allowed
-Verified DNS to ensure WSUS resolves to the wsus server.
-Verified GPO's to ensure they were accepting GPO that directs workstations to point to http://wsus:8530
-Performed wuauclt.exe /resetauthorization /detectnow; /detectnow /updatenow; and /reportnow commands from command prompt.
-Verified all WSUS folder permissions were set properly.
Customer reports no changes were made to system. This began affecting all clients on same day approx 3 weeks ago.
My next thoughts would be to modify the GPO to try and access the WSUS server via IP instead of DNS. Also possibly reinstall WUA on one of the workstations to see if this corrects the issue.
Anyone else have any recommendations for troubleshooting steps?
