Help !!!
We have a VPN setup between a main office and four remote offices,
each remote office has a single PC attached to the watchguard SOHO6
firewall.
Our main office has a watchguard X700 with 30 PCs including two
Windows 2003 servers. Both servers has Active directory running and
are DNS servers. One server is used for file storage and printer
sharing the other has exchange 2003 and RRAS running to allow a
single sales rep to dial in from his laptop whilst out of the
office.
The fileserver also has WINS configured, all clients are configured to
point at both internal DNS servers and the WINS server.
All clients and servers have static IP addresses so no DHCP.
I have noticed that the email server has been given an extra IP
address (that appears to work) by RRAS which is also registered in
DNS.
Everything appeared to work perfectly until about two months ago, now
our VPN users loose communications with the exchange server every two
to three weeks.
They can still access the fileserver and can still ping the email
server, but I cannot browse their PCs from the server and they cannot
connect to exchange either via OWA or outlook.
Non VPN users are completely unaffected by this and the only way to
restore VPN access is to reboot the email server.
Can anyone help?
