Can't authenticate/No USRMGR/MSBROWSE

By tinman6 ·
We are a single domain with three DCs, each in seperate subnets. We have two WINS servers residing in seperate subnets from each other, one of the resides in the same subnet as the PDC. We have eight seperate subnets that are active. We have set the regestry hack on login to not allow Win9x sharing, so the 9x machines will not participate in browser elections. We are using 10.* addresses with subnet mask of 10.x.255.255. We are using Nortel switches and Marconi ATM for backbone.

Now the problem. Each day we atre having to come in and reboot our PDC so that users can authenticate. before we reboot we can not access User manager or Server manager. Once we reboot everything seems to be fine. We have initialized our WINS servers thinking that the problem may be there, but to no avail. We have noticed frequent browser elections throught the day. As soon as we reboot the PDC the MSBROWSE entry is on the PDC in WINS, but shortly after another machine will grab it. The Domain(1B) entry is however consistently with the PDC. When the situation occurrs we are unable to ping the PDC via hostname.

Help would be greatly appreciated.

Have you tried using a subnet mask of 245.0.0.0 ? Just curious.

We have not. Please explain what this would do for us.

If you are using 10.x.x.x addresses then your network is classified as a class A network. In that case your subnet mask must be 255.0.0.0. In a subnet mask, the first two octets should not be the same as the network address. I think you are having trouble because of the 10.x.255.255 you are using for your subnet mask.
Check here for my reasoning:

If you copy and paste the above URL, remove the space between the 71 and the 0to

For example, if you are using 10.10.x.x for a network address, then your subnet mask would be 255.255.0.0.

You are correct we are using a 255.255.0.0 SM. Sorry I wasn't clear.

I think you are facing the Browsing Service problem. I faced the same problem.
Check my Q/A: (Read the 2nd one especially)

Browsing Service problem???

Also check this for Browsing Issues:

Solution:
Disable the Browsing sercice on the PC which is grabbing the PDC's master browser role in Control Panel > Service.

(Better read the 2nd thread I mentioned)
