Nope. DNS is NOT running on my AD servers. My domain (i.e. dept.domain.com) is a subdomain of dept.com and dept.com's DC's are runnind DNS. the dept.domain.com DC's are pointing to ad1.domain.com and ad2.domain.com for DNS resolution which was the only way we could get replication to work correctly. This is significant since the AD servers are NOT authoritative for the DNS domain domain.com. The authoritative servers are BIND but have SRV records for ad1 and ad2 and are delegating all the "_" subdomains to ad1 and ad2. Basically the DNS in the AD domains is JUST for AD, not normal DNS.
Even so, would DNS issues cause very slow downloading of IMAP messages? I would think that by the time I made the connection and I was watching my local mailbox fill up, that DNS already did it's thing and we were long past that. --Todd. ----- Original Message ----- From: "Douglas Mays" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, October 10, 2002 8:33 AM Subject: RE: [IMail Forum] IMail SLOW after moving to 2000/AD server > Answer me this first. > > Is IMail running on a DC?
