No names, IPs only

Hi.

I moved my DHCP and WINS servers from NT4 (192.168.0.250) to W2003 (192.168.0.100) box, and now Cisco VPN clients lost name resolution – No connection to Exchange, no computers in My Network Places, cannot ping by name. They still can ping by IP address though.

Here’s a snapshot from one of the clients:

LAN Connection (via Linksys router)

IP: 192.168.0.14

Subnet: 255.255.255.0

Gateway: 192.168.0.1

DHCP: 192.168.0.1

DNS: 207.69.188.185

LAN Connection 2 (Cisco):

DNS Suffix: domainname

Description: Cisco Systems VPN Adapter

IP: 192.168.254.27

Subnet: 255.255.255.0

DNS: 192.168.0.4

WINS: 192.168.0.250

I am not sure where it takes:

DNS: 192.168.0.4

WINS: 192.168.0.250

from. These are my old servers. The new box is 192.168.0.100.

Is this information stored on the Cisco router? If so, how would I change it?

Thank you,

John

Re: No names, IPs only

John,

You should change the group information on the VPN server to match the new DNS,WINS server IP.

crypto isakmp client configuration group {the name of ur group}

dns 192.168.0.100

wins 192.168.0.100

exit

Once you have modify this info, you should be able to ipconfig /all and see the new dns,wins ip under the vpn adapter. Btw you have to reconnect the vpn client for the changes to take effect.

Hope it helps,

Re: No names, IPs only

with the existing config, it should have sth similar to this:

crypto isakmp client configuration group cisco

key cisco123

dns 192.168.0.250

wins 192.168.0.250

domain yourcompany.com

pool vpnclient

acl 100

now, to modify the dns server,

router>en

Password:

router#conf t

router(config)#crypto isakmp client configuration group cisco

router(config-isakmp-group)#no dns 192.168.0.250

router(config-isakmp-group)#no dns 192.168.0.4

router(config-isakmp-group)#dns 192.168.0.100

router(config-isakmp-group)#exit

router(config)#exit

router#wri mem

in order to obtain the new dns server settings, remote user needs to log out and log in again.
