I reposting this message. When connecting to iif.2000 via a client or dbaccess via tcp, I am noticing connect latency of up to 15 seconds (sometimes the connection is under 1 second). I get the results no matter how busy the network is. In my case, 5 users tops. I noticed in the manuals that if you have DHCP enabled, you need to have WINS enabled. As you can see from from settings below, I don't have WINS Proxy enabled by I do have a Primary WINS server installed. I placed a call with Informix, but they don't have answer yet. They are sayings its an O/S issue. OK, if it is an O/S issue, what happens when a user tries to authenticate against a NT server? What look-ups are performed?
