Exchange 2k3 Error 8207 MSExchangeFBPublish 0x80004005

All,

I have a question that is inexperienced. However, I just don't know how to do it

... here is the back story, first ....

I have the following error in my exchange server ...

Event Type:      Error
Event Source:      MSExchangeFBPublish
Event Category:      General
Event ID:      8207
Date:            11/3/2008
Time:            4:16:45 AM
User:            N/A
Computer:      MAIL
Description:
Error updating public folder with free-busy information on virtual machine MAIL. The error number is 0x80004005.

For more information, click http://www.microsoft.com/contentredirect.asp.

This error is new. The only recent change to the environment was a removal, via dcpromo of a test DC. Said DC had no role defined just AD installed. It was not a GC, DNS, WINS or FSMO holder in anyway.

I have read the following ...

... which mentioned this as a resolution ...

http://support.microsoft.com/default.aspx?scid=kb;en-us;822444

..... OK ... Now for the question ....

Because it looks like I have to reset my system folders on the exchange box, I have to use guidgen.exe to generate a registry value and I have to use ADSI Edit to execute the fix .... I know this sounds weak ... but ... I went to the link provided by MS and have not been able to find GUIDGEN.EXE for download there. Additionaly, I can load the mmc snap-in just fine for ADSI Edit ... what I don't know is how to configure the connection data to get to the data mentioned in the MS article. I have never had to use ADSI Edit or GUIDGEN and that is the reason I have no knowledge of how to use them.

Please help and enlighten me.
