Environment

ITMS 8.1 RU7

Cause

The SMP server has a file mismatch version. After previous repairs, some of those files didn't match with the expected content on them.

In this particular instance, these were the files that needed to be updated:

cfgnsclientsettingsnew.aspx
cfggeneralagentsettingsdetails.aspx
cfggeneralagentsettingsdetailsdownloads.aspx
cfggeneralagentsettingsdetailsgeneral.aspx
 

Resolution

Replace the cfgnsclientsettingsnew.aspx file with one from another SMP Server with the same ITMS version. Then refresh SMP Console and try the page again.

Also, try a Full Repair using Symantec Installation Manager (SIM) if you noticed more files that needs to be updated.
