That was it. After adding static ARP entry it fired right up.

You said you're using a VIP for WI. You wouldn't happen to be using NLB (in multicast mode), would you? If so, you'll need to put a static ARP entry (VIP to multicast MAC) into your Cisco gear for off-subnet clients to be able to get to the VIP.

When users try to ping the WI boxes and can't, is it the name resolution or the ping that failing? If the name is resolving but the ping is failing, what's a tracert show? If the name is failing to resolve, what happens if you ping the IP address of the WI servers? If you think an ACL could be blocking some traffic, try... Telnetting to a Citrix server on TCP port 1494 (use: telnet IP address 1494). If you can get to it, it should respond if an 'ICA'. Telnetting to a WI server on TCP port 80 (use: telnet IP address 80). Should come back with a blank screen.

All Citrix servers are on the same Vlan. All people on this Vlan can access Web Interface and the Citrix servers just fine. Users on another Vlan cannot access the server farm. They cannot ping the virtual IP for the Web Interface servers. At this point it appears as a Vlan configuration issue or name resolution problem since they cannot even ping the IP address. Just want to see what others do to address their Vlan issues. In know Citrix has a CTX article about Cisco router setup, however, the problem they are seeing does not appear to be a problem of browsing for publishing applications. Any suggestions?
