This weekend I was asked to look at a computer that had been giving its owner a lot of trouble. They could not visit any HTTPS sites in IE, or AOL. The computer also could not install any patches / updates, it would complain about the patches not being able to be confirmed as coming from a trusted source.
The first problem, getting the HTTPS protocol to work was easy enough. That one I just had to re-register the urlmon.dll
That was accomplished with: regsvr32 urlmon.dll
That returned the abiltiy to browse https sites. It did not, however restore any abiltiy to install active X controlls, or install and of the downloaded windows updates. I did some more browsing, and came across a list of other DLL’s to re-register.
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 dssenh.dll
regsvr32 rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 sccbase.dll
regsvr32 slbcsp.dll
regsvr32 cryptdlg.dll
After these we re-registered (initpki.dll takes forever) I tried again and everything began to work as designed. I was able to install ALL system updates and patches. I was able to access ActiveX controls, and website viewed as they were designed to be.

Sure, you may have been able to do all that, Mr. BigShot
but…..
Can you install 2 programs to a stoopid Windows server, migrate all files and debug deprecated code in UNDER 2 hours?
hmm????
I didn’t think so, sit back down
YOU are a genius and thanks loads for fixing a crippled computer!
