RE: Double-take failover
I had a somewhat similar problem. When the failover computer would take over, the alias would have trouble with my WINS server. If I removed the old (i.e. dead) server from WINS, and let the new (Failover) server register itself, I think it was fine (IIRC). That might not be your exact problem, but hopefully it points you toward a solution. -Jim Jim Holmgren MCSE, CCNA [EMAIL PROTECTED] Network Engineer Advertising.com We bring innovation to interactive communication.

RE: Double-take failover
Do you have a dedicated PDC or is it one of the Exchange Servers? On the double-take configuration are you failing one exchange server over to another or do the exchange servers failover to a dedicated target server?

There certainly is a spot to change the failover time! I have it set to 15 minutes on my Exchange server, that gives me time for the occasional reboot.

RE: Double-take failover
I have a dedicated PDC (well exchange isn't on it anyway). and yes one exchange server fails over to another exchange sever. so it works good for you? any issues with domain login after failover? are you using WINS?

On the double-take configuration are you failing one exchange server over to another or do the exchange servers failover to a dedicated target server?

RE: Double-take failover
I agree with checking your WINS servers. If you have multiple WINS servers make sure both are clearing out the Source server after the failover. Todd [EMAIL PROTECTED] 02/13/02 09:26AM I had a somewhat similar problem. When the failover computer would take over, the alias would have trouble with my WINS server. If I removed the old (i.e. dead) server from WINS, and let the new (Failover) server register itself, I think it was fine (IIRC). That might not be your exact problem, but hopefully it points you toward a solution. -Jim Jim Holmgren MCSE, CCNA [EMAIL PROTECTED] Network Engineer Advertising.com We bring innovation to interactive communication.

RE: Double-take failover
I am suspecting something is up with the WINS database. I am cetainly no expert and its time to RTFM on WINS. any advice on what to look for in there? my maintenance agreement (NSI) ran out long ago and its $1195 per server to reinstate them. I'll be trying to fix it on my own for now.

RE: Double-take failover
You can adjust the time delay from when the server fails to when it actually assumes the roll of the Target server. todd [EMAIL PROTECTED] 02/13/02 09:37AM We tested Double Take but never implemented it.
