VPN connected but cant access window's shares

By chays33 ·
I have a new Cisco 5520 connected to isp and local lan. I ran the vpn wizard and configured laptop with cisco client. I can succesfuly connect to the vpn, ping the servers, and other devices, telnet to other cisco equipment on the lan, but when I go access my network drives (windows 2003 servers) I get an error "Microsoft windows network: the local device name is already in use. Connection has not been restored. I can ping by ip address and by host name with no problem. Any help is MUCH appreciated, thanks

Ports and protocols

You need to force windows client to use TCP for domain authentication:
http://support.microsoft.com/kb/244474

Also you need to open up ports for Windows to be happy:

These are the required AD ports:

Service Port/protocol
RPC endpoint mapper
135/tcp, 135/udp

NetBIOS name service
137/tcp, 137/udp

NetBIOS datagram service
138/udp

NetBIOS session service
139/tcp

RPC static port for AD replication
<fixed-port>/tcp

SMB over IP (Microsoft-DS)
445/tcp, 445/udp

LDAP
389/tcp

LDAP over SSL
636/tcp

Global catalog LDAP
3268/tcp

Global catalog LDAP over SSL
3269/tcp

Kerberos
88/tcp, 88/udp

DNS
53/tcp, 53/udp

WINS resolution (if required)
1512/tcp, 1512/udp

WINS replication (if required)
42/tcp, 42/udp
