We are in the process of switching from TokenRing to Ethernet. After configuring the new network card to AutoSense we have been getting the error window stating that the Domain Controller can't be found. The strange thing is that we can open all network drives, they get emails, etc. Tried to change the autosense to 10/100 but continue to get the same message. Any ideas?

If you are working with NT, you might have to manually set the domain controller in the lmhosts file located in c:\winnt\system32\drivers\etc\lmhosts.

I believe the format is:
#PRE
" \0x1b" #PRE

make sure that the second line with the domain in quotes are EXACTLY 20 spaces.
" \0x1b"
"12345678901234567890"
\0x1b is for primary domain controller
\0x14 is for backup domain controller

Hope this helps

Force the card to 10 MB half duplex or if your switch is 100 MB force it to use 100MB half duplex.

Autosensing is a pain ecspecially on servers this is an option that really should not be used.....

Hope that helps....

I faced the same problem in some other way:

sol: check the lan card link setting and modify all link setting (manually) to 10mbps or 100mbps as per your network. ie if hub is of 10mbps change all to 10mbps else...

but i am sure this problem isnot because of domain controller.

I also don't think this was a domain controller problem. I did find that if logon was delayed for 2 min. there was no window indicating no domain controller. Maybe it is something with the speed of our new Cisco equipment. We are still running both Token and Ethernet until everyone is switched.

I wanted to make sure that my previous answer was clear since it was a bit vague about where to put the entries. The lmhost entries don't go on the domain controller. It goes on the client machine. I just wanted to make sure that that is what yougot from it. Just making sure.
