Ok I have tried a couple of new things on this and it is still not working. I changed the Reverse DNS to use the DMZ host rather than the domain controller. Still no go. I was confused as to why my Kerberos packets were being reported as Fragmented in my ISA logs (any insight on this would be appreciated) so I decided to bypass the firewall. I went ahead and used VPN to gain access to the domain. Now I am on the network and I thought for sure the authentication would be allowed. Still no good. Still the same error. Any help would be appreciated. Thank you. -----Original Message----- From: Stephen Herrera [mailto:sherrera@xxxxxxxxxx] Sent: Wednesday, February 06, 2002 9:24 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Itradomain Communications http://www.ISAserver.org Does anyone have any insight on this? I have triple checked everything, scoured logs....not making much sense. Any help would be appreciated. Steve http://www.ISAserver.org Hello all, Just wodering if anyone else has tried the Intradomain Communications Lab. I have gotten all the way to the point where it asks for credentials to add a machine to the domain. When I enter in the info and select ok it hangs there for quite a while and then tells me: "The following error occurred attempting to join the domain 'mydomain.com' The specified network name is no longer available." Has anyone seen this or have any ideas? Soooooo close yet so far. Even though I realize this is not the most secure setup it's a way cool lab to go through. steve ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: sherrera@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: sherrera@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
