A8N-Sli MB-working Ethernet onboard- SmB server "Connection Failed"

Zephy thanks for 10.5.1, 10.5.2 rev.1 and 10.5.2 Rev. 2. I greatly appreciate it.
Zephyroth Leopard 10.5.2 amd Rev. 2
I have an Asus A8N-Sli motherboard, Onboard Lan Ethernet is connected and working, I have all setup parameters set correctly. Forgive me if any of this is duplication to what might have been posted, I did scour the web for a possible fix on this.

Problem: Ethernet onboard Lan is connected and working. When I try and connect to server it states a wierd error message " not a valid Url Address". When I try and connect to the server in the side bar, it says "Connection Failed"

After spending days trying to resolve this by searching forums, I re-installed Zephyroth 10.5.2 amd Rev. 1

Everything works perfectly in this version.

IS THERE A FIX FOR THE "CONNECTION FAILED" ERROR IN 10.5.2 Amd Rev. 2.
If not I am very grateful for 10.5.2 rev. 1

Very thankful,
Miche Bre
