Yes you will have problems with the SIDs in both cases. When you bring the new machine up you will have to first remove the old server from the domain and recreate a new entry with the same name. (Or allow the machine to create it during the install). If you wanted to bring the old machine back then you would have to remove and recreate the server name again.
-----Original Message----- From: Zach Mathew [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 27, 2002 12:53 PM To: MS-Exchange Admin Issues Subject: Moving Exchange Server 5.5 Anyone know of any issues if you try to bring a new NT 4 server into a domain using the same computer name as the old server? We are planning to move our current Exchange server 5.5 to a Compaq ML370 with 3-18 gig drives running RAID 5. The plan is to shut down the old server, install NT 4 SP6a and Exchange 5.5 Enterprise ed. on the new server and use the same server name as the old. If the install goes sour we would like to be able to bring the old server back online till problems are resolved. Would we run into problems with the SIDs (or any other problems) if we attempt to bring the old server back online once the new server is joined to the domain? Also, the existing Exchange server is a BDC as will be the new one. Would appreciate any thoughts/advice. Thanks.
