Hi,

I'm using windows 2000 professional on a laptop thats a memeber of my domain. The laptop has got a dialin account configured and safenet vpn client installed. On the office network, a 3com internet firewall dmz is installed to secure internet access and provide vpn capabilities. So, I dial in and ping to the lan ip address of the server (192.168.0.1), the safenet client establishes the vpn connection and it the ping gets a reply. So, the vpn works. But when I want to to e.g. net use \\192.168.0.1\ipc$ or net use x: \\192.168.0.1\data, I get the following error : No domian controller available. ???

When I logon to the notbook locally (not choosing the domain profile) it all works fine ...

HELP

It sounds as though name resolution to the DC is broken.  Can you ping the DC by name?

What is the OS of the server that you cannot reach?

The exact error is "There are currently no logon servers available to service the logon request"

You should check your WINS on the server.  I think the client might be querying the WINS for the DC and it is returning a different address.

I'm running wins and it's working fine. I even added the wins server in the dialup conncetion. Next to that, I've added 1c records for the domain and the dc in my lnhosts...

Maybe this is a cached credentials problem.  Have you tried to do a connect as?


1. Right-click My Computer, and then click Map Network Drive.

2. Map the drive letter and the folder.

3. Click "Connect using a different user name".

4. Enter the credentials in the universal naming convention (UNC)
   "Domain\Username" format.

5. In the password box, enter a password.

6. Click OK.

geoffryn,

I dont'wan't to be rude, but if I don't know how to perform some action, I wll ask you, saves us both some time.

I'm holding some info from you, the laptop is memeber of the domain. When I log, I can choose from two options, the domain and local. when I log on to the local to the laptop, all the net use commands work, when I log on to the domain, the net use command don't work.

I'm 100% sure that my credentials are ok...

That is a sign of cached credential problems.  A local account will not be caching creds for the domain.

You were right about htis, when I make a network connection and use the administrator@mydomain.com account (same account as I'm logged in as) it works, after that, I can net use what I want...

But after a reboot, I must make a network connection as the domain admin and then I can use it again... How can I solve this ?

I don't think you can.  You would have to force the domain back to NTLM and disable Kerberos.  A work around might be to create a local account with the same user name and password and use pass-thru authentication
