Encountered this before in Ex5.5 when different machines have different SP level two yrs ago. One co-worker updated one machine from SP2 to SP3 without informing us. I do a few thing, shutdown and remove the offending server from the site in the Administrator program, and go to admin raw mode to modify the file version as in this technet article. http://support.microsoft.com/default.aspx?scid=kb;en-us;158336 This step is risky for this case because of SP4. Read somewhere SP4 is non-reversible. You can't backout from SP4. Ask an expert on another list before abt SP4, he informed me there are some schema change to prepare for migration to active directory and Ex2k. So have to be very careful on this. Personally I will advise against the step in the article. -----Original Message----- From: Dhaval Brahmbhatt [mailto:Dhaval@xxxxxxxxxxx] Sent: Friday, November 29, 2002 7:48 PM To: [ExchangeList] Subject: [exchangelist] RE: Error when try to create new email account http://www.MSExchange.org/ I think you need same SP on both the servers.
