I have just installed a windows 2000 server - run dcpromo - and connected the win 2000 DC server on the same subnet (LAN)as my NT 4 domain. I have also setup a two-way trust relationship but, I still cannot access/map to a shared drive on the NT4 PDC from the win 2000 DC? Is there something wrong (WINS? or LMHOSTS? - I may have forgotten?) ideally, for the time being I ony want to allow my NT 4 users (on the NT4 domain to access resources (shares etc) on the new Win 2000 DC.

>run dcpromo
why did you do this, why not just leave the w2k box as a member server
If you are trying to upgrade your network to w2k, the recommended way is to upgrade the PDC and run dc promo on it
dcpromo makes it want to be the boss, and since there were no other w2k boxes, it see itself as the only tree in the forest, and the NT box can't be the PDC to it

Win2KS in native mode (and it sounds like this is what you are in) depends on and requires DNS. What DNS server is in use? Does it have all the appropriate entries?

Add the NT4 GLOBAL Domain Admins Group to the W2k LOCAL Admins Group.

Add the NT4 GLOBAL Users Group to the W2k LOCAL Users Group.

If You want more individual credentials, then:

Create a W2k LOCAL Group, and give this group the wanted NTFS-permissions on the W2k-resource (share/path).

Create a NT4 GLOBAL Group, add only the wanted NT4 Domain users to this new Group, and add this new group to the new W2k LOCAL Group.

Thanks everyone for your comments - seems like the LMHOSTs option is the most pragmatic approach (also the easiest)!
However, if I want to make use of AD & DNS in maintaining a mixed environment - until I can start to install the other WIN 2000 servers and migrate the NT resources - what should I do? Where do I start?

I am afraid that both AD & DNS are a bit of a mystery to me(suppose that's the price to pay for having a single NT domain model. for so long!)

More importantly - Thanks for your kind (and most useful) contributions, so far. Regards!

AD is completely dependednt upon DNS, if DNS is not configured properly you'll know.  Win2k and XP both go to DNS for name resolution first, they were built around that.  While the LMHosts solution is what you are looking for here, it should not be your long term solution.

I agree with StevenLewis, upgrading your Domain will be the long termm path of least resistence.

You cannot have both Win 2000 and NT4 be the PDC at the same time within the same domain.  You have to demote the Win 2000 to a BDC then connect it to the network.
