Hi, Thanks to share your post. For the issue, do you mean that you meet error 27745 and some other errors? I just wonder what the operation that you have taken. The possible cause should be due to the moving of a site collection or a content database. To resolve this issue, you should run "stsadm -o sync -deleteolddatabases n". It deletes old records corresponding to these databases that have not been synchronized since n days. If you want to know more about this command, please refer to this: http://technet.microsoft.com/en-us/library/cc263196.aspx. And you may also check the error in ULS logs located in %COMMONPROGRAMFILES%\Microsoft Shared\Web server extensions\12\LOGS. One guy has met a similar problem and he has resolve it, hope it may also give you a hand: http://social.technet.microsoft.com/Forums/en-US/sharepointadmin/thread/70c4716d-cff2-41ee-bac8-92f49805364e.
