Disclaimer: I am posting this SCO post here because it is possibly a network issue

I am running SCO Open server 5.0
as far as I know nothing has changed on my network but last week out of the blue when some of my users (NOT ALL !!) try telneting into my server there is a horrible delay close to 90 sec. before they get a log in prompt

I have brought down my whole network (all switches, computers, servers, printers, network copiers ) and am still having an issue

the users are on different segments of my network so I can't blame it on a switch going bad.

Does anybody a clue where I should go from here ?

Use a packet sniffer to examine a faulty network session between a client and the server.
If the server and client are not on the same LAN-segment, you might need to sniff both their individual segments to catch possible filtering along the route.
Perhaps your server is trying to do an ident check that gets filtered?
At least you will find which party in the communication is causing the delay.

You might want to compare your captured frames with that of a correctly working session, if you still can't find the source of the problem.

Thank you but I figured it out last night with the help of some kind posters on the SCO board

it turned out to be a unix/DNS issue and thankfully it is now resolved.

Well, you would've caught that with a sniffer too.
