Re: Unable to connect to UNC or IP addresses by name but able to ping

I support a remote site lets call it site B. At site B we use
sonicwall IP Sec tunnels to connect 25 or so pcs and 3 servers (2 of
which are 2000 DC's), to site A. The client machines and servers use
this tunnel from a Site B (192.168.44.0) to connect Site A
(192.168.1.0) which contains additional DC's and our primary and only
exchange server.

Up until about a month ago everything worked fine between the sites
and we could replicate DNS etc client pcs could browse files on both
sides using unc names or unc ip mappings. Then it basically stopped
working, our tunnel is up and connected and we can pint by name and
IP address but are unable to go beyond that.

The critical issue is that our exchange server (Site A) is not at
site B and now outlook clients cannot connect to exchange internally
at Site B thus no email. DNS replication is also failing as they
sites cannot connect using AD synch either, so now AD is also not
able to replicate changes from site to site.
Site B geographically is 2000 miles from Site A so we are trying to
get this done remotely. We do have remote access in using IP mapping.

At this point we have spent countless hours on phone getting no good
response from MS support as we are also a MS partner. Additionally
we have replaced the soncicwall appliance at site B, added host files
on all pcs and several other steps with no good result. We have
basically hit the wall and have no idea what would be causing this
issue. If anyone has any suggestion or has experienced this before
it would greatly help us if any suggestions could be made. I
actually think it could be something very simple but we are so far in
we may not just see it.

We are stumped on this so any suggestions would be great!

Thanks
Mike
