2x ThinClient Error Code: TCAC008

Hello all, we work with a number of customers who use the 2x ThinClient software. It enables PXE booting of machines into a ThinClient which then connects to a Terminal Services or Citrix environment. The server has been working perfectly well without any problems for the past six – seven months, but today we recieved the following error:

2x Thin Client Error TCAC008

2x ThinClientOS Error

Could not register a ThinClient session on the server. (TCAC008)

The 2x website doesn’t have an article which relates to this, so I thought I’d share it here. For some reason the 2x ThinClient Server had lost its licensing information, so we quickly re-entered it and restarted our ThinClients and they booted up correctly. (Hurray!)

Cisco Router Static DHCP Bindings

When using a Cisco router to serve DHCP Requests, it’s not immediately obvious how-to create reservations for a DHCP Pool. If the device has already picked up an IP Address via DHCP you will need to first remove the DHCP Binding by running the follow command:

clear ip dhcp binding 192.168.0.x (IP Address of the device)

This is the configuration which I have used on a Cisco 1841 Router:

ip dhcp pool name-pool
import all
network 192.168.0.0 255.255.255.0
default-router 192.168.0.254
dns-server 192.168.0.1 192.168.0.2
lease 0 2
!
ip dhcp pool name-pool-static
host 192.168.0.253 255.255.255.0
client-identifier 0100.xxxx.xxxx.xx (MAC Address of the device)

To verify this, use the follow command from exec mode:

Router# show ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Hardware address/ User name   Lease expiration    Type
192.168.113.249 0100.xxxx.xxxx.xx                   Infinite            Manual

After my Trampy PC (it was found in a bin) decided to self destruct, I thought I’d try something new… So I bought a Mac Mini, I didn’t want to spend mega bucks so I thought this would be a pretty cool option. I didn’t take too much convincing after I managed to blag Student Discount on it in the Apple Store, yippy! 🙂

I’m pretty impressed with this little machine, its got pretty good specs for the price tag. Not that specs matter as all I use my PC (or should I say Mac now) for is Facebook and Email!

I will hopefully start building some websites soon, so I will be trying to keep this place up to date.
