HI.

I don't see something wrong with the config.

What is the pix version?

> I obtain from PIX the deny message for UDP 138, UDP 137, 1056 and 1058
Can you post the exact error messages, and more details?
Can you ping via the VPN tunnel?
Can you telnet/http/ftp via the VPN tunnel?
Can you connect to MS servers without browsing (using UNC path and/or IP address)?

Please describe the client environment (OS, client version, connection to ISP, network devices and software firewalls, etc).

Hi
This is the situation:
1)
The VPN Client send this command: NET VIEW COMPUTER1
The PIX log contain Deny UDP 138 - Deny UDP 137 - Deny UDP 1056 - Deny UDP 1058
The VPN Client obtain error to browse network.

2)
The VPN Client send this command: NET VIEW 192.168.1.20 (COMPUTER1 IP Address)
The VPN Client obtain the browse of shred resource

Regards.

HI.

You can deploy LMHOSTS or HOSTS file to remote clients, and/or check your WINS/DNS implementation.

The solutions depend on OS of the remote client, OS and configuration of internal servers, and other OS and name resolution related factors.
