I was passed what I though was an easy one earlier, SBS 2003 server RDP console failed to run, I checked the mstsc.exe & mstscax.dll files and the version number didn’t match so I replaced both files with correct versions and tested, all worked perfectly.
10 mins later I was told it didn’t work again, checked the version numbers, they were different again, replaced the files again then ran mstsc.exe worked perfectly, closed the app, checked the version number it had changed again….
WTF?!? What keeps replacing the file with an older version??, I’ve disabled volume shadow copies & AV and within about 15 seconds of replacing the file with the correct version the old version takes its place…???
