We installed Exchange SP4 on our machine afterwhich we no longer cannot create/modify the mailboxes. The message keeps telling us that the file version of inproxy.dll is wrong and the program could not find one in the server. When I checked this out at /Organization names/site name/server/properties the build is for SP3 and when I looked for the DLLs I found that they are from SP4. I'm not sure if I should follow MS KB Article 158336. It would seem that to correct this I need to copy the DLL from SP3 or change the file versions.
Any suggestions will be highly appreciated.

Thanks

I think that you would have a greater response on an echange forum I work with 5.5 for a while but am afraid I didn't delve into it to deeply try here: http://www.msexchange.org/
