VMware Server Network Issues

Client called me in to setup a VMware Server 2.02 based 2003 R2 server as a second DC. He prebuilt the VM and I'm just joining to the domain and making it a DC (small DFS later).

Anyway, he HAD networking working at his place before he brought the physical box to the site and now, after changing the IP to operate on the current location's network (192.168.1.x (was on 192.168.111.x)) the VM cannot get out of the .1 network.  It CAN use the DNS server on the lan and ping the gateway (192.168.1.10 and 192.168.1.1 respectively) but the gateway doesn't seem to want to route traffic from the VM. (The VM NIC is in bridged mode and I've tried NAT mode with no luck)

So, to summarize:
LAN 192.168.1.x
Mask: 255.255.255.0
GW: 192.168.1.1

Host:
IP: 192.168.1.11
Mask: 255.255.255.0
GW: 192.168.1.1
DNS: 192.168.1.10

VM:
IP: 192.168.1.12
Mask: 255.255.255.0
GW: 192.168.1.1
DNS: 192.168.1.10

NOTE and to be clear - when pinging google.com from the VM, it DOES resolve - but gets request timed out responses.

Haven't rebooted yet so I'll do that now, but failing that, Any ideas on how to get full internet access back on the VM?  (The host works fine; posting from it).

Update: MAY NOT be VMWare Issue.  Finding another PC we're adding is also experiencing the same issue with no VM on it.  BUT, the VM Host is working and other PCs are too... (No apparent IP Conflicts).

Probably the easiest thing to do is uninstall and reinstall VMware Server. Occassionally it gets confused by host networking changes.

It also may help to go into the virtual network editor, and where it says bridge to automatically chosen adapter, be specific and specify the adapter you want to bridge to.

An important part of learning any new piece of software is understanding the terminology it uses. Thankfully WordPress uses fairly simple names for everything that make it easy to start using the software.

OK, just saw your update.. What kind of switch do you have in your network? Is it managed? can you check the ARP/CAM table in the switch?

It's a small network - using a SonicWall Firewall - trying to get login and model info.  I was suspecting that might have some kind of connection limit, so that's what we're checking on at the moment.

Ok, it was the SonicWall Firewall (SOHO3) - has a maximum connection limit of 25 and we hit it.  Rebooting the firewall (and first shutting off a few devices - getting rid of gateway info on printers and other non-essential devices) resolved the issue.
