Connecting a laptop on two sites

By Matt_Jones ·
I have two NT4 domains with DHCP servers on seperate sites with a two way trust relationship. Several users work mainly on Site One, but do work from Site Two occasionally. They use laptops with docking stations, and so hold different profiles for each docking station.
One of my users has stopped being able to log in on Site Two. She cannot connect through the Site Two router to access her Logon Server on Site One.
If I manually assign her an IP address in the scope of the Site One DHCP server she connects with no problems. No other user is affected. The only difference is that she is running Win95, whilst everyone else is running Win2000. The rub is that it used to work. As far as I am aware, nothing has changed on the server side.

It's been a while since I've even seen Win95, but as I recall the login to an NT Domain is a bit "different". If I am not mistaken (and I probably am...) the user is not asked at login "to which NT Domain", like they would be if using NT4Wkstn, for example. Instead, the NT Domain for the user is "hidden" inside some Properties sheet.

That is where I would check.

The "real fix" is obviously scrap Win95, but since this user is STILL using this piece of junk after too many years, there must be a good reason.

You set the Domain in Network Neighbourhood - This is set correctly.

I agree with you about Win95. However, I bet there are more installations out there running Win 95 than there are running NT and 2000 combined. Such is life.

I had a similar problem that was caused by WINS. The problem was that when a computer left domain A, it's name was still registered in the WINS database for 3 days (this is a setting you can fix in WINS), so that when the user logged on at domain B,it checked the computer name in the WINS database, and sent back an IP address for Domain A. In order to get this to work, I eventually ended up disabling WINS database replication between the two domains. There is probably a less drastic solution, but I didn't really need WINS.

I am not trying to log onto two domains. The user needs to log on to one account on one domain from base stations on two sites. The two sites have a two way trust relationship set up.

I've had a similar problem. My problem was that the user on boot still had a valid lease on an IP address, ands wasn't asking for a new one on boot. You have three choices:
1) Set the DHCP lease times short enough on both domains that a user's PC will attempt to renew the old one on boot (like 1-2 days)
2) Teach the user how to release their old address manually when they go to a new place
3) Release the old IP address on boot before connecting to the network using a script

Because there are two docking stations involved, each with their own inbuilt NIC cards, each one has a different profile, and stores a different IP address.
If I set it up with one common static IP address it works. But obviously this is not an ideal solution.
