Server Cannot Ping The Switch It's Connected To
I have 6 servers all with W2K3.
I have 4 managed switches (Dell Powerconnect 24 port POE)
All the servers are plugged into switch #1 and all other switches are downstream (not stacked)
Two of my servers (terminal server and backup DC) cannot ping switch #1 or switch#2. However, they can ping switch #3 and #4 and everything else on the network.
The other servers ping everything just fine including all 4 switches.
Also, all workstations can ping everything including the two servers with the issue.
Could this be a service related issue? I cant understand why they can ping addresses beyond the switch but not the switch itself.
For clarity:
switch #1 = 10.0.0.205
switch #2 = 10.0.0.206
switch #3 = 10.0.0.207
switch #4 = 10.0.0.209
Terminal Server = 10.0.2.10
Backup DC = 10.0.2.20
Ok...so I thought this was a subnet issue. But both servers can ping 10.0.0.207 and 10.0.0.209
all other servers are on the same subnet as the switches.
Now I wonder if it could be a VLAN issue. The first two switches (that I cannot ping) were already set up. The PVID on the ports for the servers are set to 1 whereas all the ports on the two switched I can ping are set to PVID 2.

Are there any VLANs or tagged ports that may be causing an issue? I would clear arp on all and try again.
ASKER
All the ports are tagged...we have a shoretel system and the workstations are connected to the phones.
I'll try to clear the arp

Regarding tagging I was thinking along the lines of make sure the interconnecting links were tagged for all VLANs.
Sounds like the 2 switches that you cant ping from the 2 servers are not setup for both PVIDs. If you want the switches manageable from any device they have to added to both.
ASKER
Both switches are setup for both PVIDs.
I can ping the switch from any workstation and I can ping any device from the switch. It's simply the two servers that conaaot ping the first two switches in the line. The 3 other servers can ping all the switches

This led me to the problem. There was a definite misconfiguration with PVIDs. There are two separate phone networks on separate PVIDs that were apparently conflicting at t he first switch.
