Software Firewall?

by luc_andre In reply to might be dhcp or dns

If you have a software firewall, like Norton Security, it could be blocking the allowance of network connections like File Sharing and NetBios (in Norton, found under Advanced Settings > Networking)

XP home

I have seen the same issue, it appears to be a shortcoming of XP home. It has issues connecting to certain network reosurces on a Domain. Only way I found around it was to upgrade the end-user to XP pro, which instantly resolved the issue.

I believe it's an issue with XP home not authenticating properly to an AD Domain.

XP Home

by vlape In reply to XP home

I have never had an issue with XP Home or Media edition authenticating against a domain via VPN. The operating system has no relevance. if DHCP is not passing thru the proper information such as domain suffix, dns, gateway because the firewall is not configured to do as such you will have a problem accessing network resources by name.

Installing another operating system is NOT the answer to this problem. Proper configuration of your firewall is the solution.

by Kjell_Andorsen In reply to XP Home

I've had the Win XP Home users AUTHENTICATE and be able to log on to VPN, that was not the problem, but the problem is that because XP home doesn't support Group policy and File level access control, they were not able to access network drives and folders on the network once they had logged on to the domain. This appears to be the problem the poster is having, and I don't really see it as being a firewall issue. The test is of course to simply disable the firewall on the VPN client and see if it works.

i am not going to get into a flame match with you about this however you are WAY off the mark here. A NON DOMAIN computer making a VPN connection to a domain will NEVER process a gp. the workstation does not even know the domain controller exists. File access control had nothing to do with the clent computer being part of the domain, this is why users have the ability to auth with user@domain or domain\user. This authentication is done when the VPN connection is established. (remember the user is authenticating NOT the machine)

This is nothing more than a firewall configuration issue. The firewall is not handling dns from vpn side to internal and most likeley the user did not properly setup dhcp relay agent or configure dhcp properly therefore the client pc is not getting enough information to use netbios names over the netowrk. I would bet anything he can connect using IP addresses to everything on his netowrk wothout any problems.

I am sure the poster appriciates your help / information however if you do not completely know that you are talking about and provide incorrect informaiton it will only add confusion to the situation. Anyhow just my two cents.

Same problem

by scottmelcher In reply to But see...

I have set up my XP home to accept incoming connections via a VPN. I am able to connect to this VPN fine from outside my network. However, I cannot then map a drive. I have tried disabling the firewall to no avail.

network adapters?

by ameza In reply to One more thing

how many network adapters do you have on the server? for full VPN functionality you need two.

dhcp relay agent or configure dhcp

by blaynepeacock In reply to But see...

Dear vlape:

forgive my ignorance, but would a normal wireless router have the dhcp relay agent you mentioned? Other than setting up the router firewall seeting to allow the VPN traffic, how to I alter the DHCP settings?
