comment DNS of site fails to resolve only on IE - 'This page can't be displayed'
Try turning on/off Protected Mode; IE > Tools > Internet Options > Enable Protected Mode. I've seen this happen with IE11 on some vendor portals as well; had to downgrade to IE10.

comment How do I get Citrix to authenticate to my new AD servers?
If I echo %logonserver% it shows I'm using my new DNS/AD server. nslookup shows I'm using my new DNS/AD server. If I do a DNS query, it shows it's querying against the new DNS/AD server, but it lists the old DNS servers. I removed the old DNS servers from the list from my new DNS server, but I still cannot authenticate to Citrix with domain credentials

comment How do I get Citrix to authenticate to my new AD servers?
1) The DNS servers are the AD servers. The settings were updated in the TCP/IP settings. The old servers were brought back up, but that hasn't resolved the issue. 2) Windows Server 2000 SP4. Old DCs were Windows Server 2003. New are Windows Server 2012.

comment Why am I unable to tracert to an IP on my desktop, but I can on my server?
Ok, I think I found the problem. The static route on the remote end for the local desktop network is going through a different route than the route for the remote server, which would explain why it's not routing properly. I'll need to test it tonight.

comment How do I connect two Cisco Catalyst 2950 over LAN?
I did that and it didn't work. I came to the conclusion there was something wrong with the firmware since other switches were able to be configured with this same configuration. Thanks though.

@rex the port-channel is configured on both sides. I have SwitchA already working with multiple ports on channel-group 1 connecting to another switch already and it's working fine. It seems the problem is with SwitchB. Whether I configure it with or without the port-channel, show int po1 switchport on SwitchB shows my changes, but show int port-channel 1 trunk and show int fa0/1 trunk do not reflect those changes on SwitchB.

I deleted the vlan.dat and recreated the vlans manually, but that didn't seem to help.

I updated the question to reflect the change I made. I've tried both channel-group 1 mode active and channel-group 1 mode on, and neither have made a difference.

comment How do I connect two Cisco Catalyst 2950 over LAN?
On the 2950, it looks like i don't have that option to set the MDIX to auto. I'm fairly certain now the issue is vlan related, but I don't understand why the switch won't let me add/remove vlans from a trunk.

The port-channel was recommended from Cisco's documentation. I tried adding the vlan to Fa0/1, but no go. For some reason, the config won't update when I issue that change. I'm not sure I need a cross-over cable since I'm able to communicate properly with another switch using standard straight-through cables, but it's worth a shot.

I updated my question with the relevant information. I have vlan traffic I need to be able to get across both switches (VOIP, wifi, etc...) SwitchA has been in the environment for years. SwitchB used to be in a different area, but I was unable to get the trunking working between both switches. I have since cleared the config on SwitchB and I am here now.
