I may be missing the boat here and simply telling you what you already know but 3 people in my office all experienced the same issue when installed Mercury QC and noone knew what was going on….. Our WINLOGON.INI file was wiped out in the C:\WINDOWS directory.

Well it turns out when you turn off UAC (Windows Vista User Access Control) it takes you to a different place giving you the “opportunity” to create a new SAPLOGON.INI file!!! If you turn UAC back on your old INI file magically reappears. If you want UAC off, because it’s a major PAIN and some programs don’t work well with it on (Mercury Quality Center is one), then make a copy, turn UAC off and then copy the INI file to the C:\WINDOWS directory and you are good to go.

Can’t wait until they sunset Vista !!!

  1. Hi,
    Thanks for this valuable information. few days back my collegue wants to re-insatll the SAP and in-order to save the time to put all the servers name in SAP Log-on Pad he tries searching for .INI file, but failed to get the same.

    Now i gets to know whats the reason , might the UAC is OFF for him.

    I was wondering where the saplogon.ini file was in my Vista system. I finally found out. It seems that it has been moved in both Vista and Windows 7. At least I found it in the following path C:\Users\\AppData\Local\VirtualStore\Windows\
