Internet Authenication Service

[Guest carthman]

Hi hoping this group can help. I have IAS running on W2k3 server. When a

client tries to authenicate the service stops with the following error...

 

"The Internet Authentication Service service terminated with the following

error:

 

Only one usage of each socket address (protocol/network address/port) is

normally permitted.

 

 

I have tried reinstalling IAS, still get same errors. Any ideas??

Hello - I came across your post when I encountered the same issue that you

were. When the IAS service started, the error: "Only one usage of each

socket address..." appeared. I discovered that IAS has specific ports on

which to connect (1812 and 1645 for authentication, and 1813 and 1646 for

accounting). I checked IAS and removed 1645 and 1646. Once removed, IAS

service stayed running. You might check this out too. Here is a link that

will help you to reconfigure IAS:

Toby,

 

It's 8pm and i have spent all weekend installing a new SBS server only to

have this error. I was about to completely lose it until I saw your post.

 

You have saved me from having a nervous breakdown!

 

THANK YOU!

RE: Internet Authenication Service

 

Apparently, after installing MS08-037 (updates 951746 and 951748) Ipsec will

randomly go into block mode and block all traffic to the server after a

restart. After chasing this error around I found a solution on the ‘net.

The update is to combat DNS spoofing. MS in their infinite wisdom chose to

change the port DNS listens on. Before it would pick a port in the 2500

range, now it picks ports in the range of 1024-60000. When it picks a port

that’s required for another service, IPSEC freaks out, crashes and goes into

block mode and allows no connectivity to the server. Mike has run into this

problem at least twice in the last couple of days. The fix is to edit the

registry and add port reservations for IAS, L2TP, AUTD and IPSEC. A reboot

is needed to put the fix into effect.
