Unable to access PC

[MatthewL]

Got a bit of an odd one and what I thought would be local windows firewall doesn't appear to be the case so want to see if I am missing anything.

 

I have site A with lets call it PCA and PCB on, there is also a printer on site.

I have my data centre with SERVERA and SERVERB on.

I have site B with lets call is PCC on.

 

Neither site can talk to each other its basically site to data centre. I want to be able to connect from PCA to PCC so so have added routing and firewall rules in sites talk. All goes via data centre. Note PCA is a workgroup PC, rest are domain joined.

 

So PCA and PCB on site can talk and they can also talk and browse to PCC.

PC3 can ping but not browse PCA, but can browse PCB.

SERVERA and SERVERB can talk to anything.

 

Firewall on PCA is turned off and have put a rule to allow connectivity but nothing. Connectivity to site is fine and I can also browse printer but just not this PC. Note there are other's say PCD and PCE setup in same way as PCA and get same results with them so sure its down to something on these machines as not installed and managed by us. Normally I would expect to be prompted for username and password.

 

Any thoughts?

Can you ping everything by IP address, but not everything by name?

[MatthewL]

I can ping everything, but I cannot access this device by IP. I can connect to other devices on that LAN so the VPN is working correctly just these PC's. First call was firewall on PC but its off.
