IAS extensionDLLs crash

IAS extensionDLLs crash

Post by doctore0 » Thu, 23 Oct 2008 15:56:38

Hi there,

I am trying to setup an IAS extensionDLLs, however my dll keeps
crashing IAS when receiving Radius client requests.

- Windows Server Enterprise Edition
- Tracing activated for IAS (netsh ras set tracing * enable)
- IAS isolated on its own svchost.exe (for troubleshooting purpose

My dll:
- RadiusExtensionProcess2 function which return always NO_ERROR (for
the moment).
- ISASAM.log
Invoking extension Ext.dll
RadiusExtensionProcess2 returned 0

Application events:
- EventID 1000
"Faulting applicaiton svchost.exe, version 5.2.3790.3959, faulting
module msvcrt.dll, version 7.0.3790.3959, fault address 0x0003396a"

System events:
- Event ID 7034
"The Internet Authentication Service service terminated
unexpectedly. It has done this 3 time(s)."

I am not a guru developper, but as far as I have understand, if
RadiusExtensionProcess2 returns NO_ERROR, IAS should then process the
request normally.

Does anyone has an idea why IAS crash and/or how can I try to debug
Thanks in advance,


1. IAS and intel wireless software give IAS Error 16 (Reason-Code)=16

2. IAS L2TP Port Loss?After Install IAS

After Installing SP1 All Ports in RRAS Show Default settings ie.. 5 PPTP
5L2TP.Then when I install IAS I lose the five L2Tp Ports.I can reactivate
them in RRAS\ports however I show a loss of several Client IP's with RAS
unique ID's in DHCP.I havent set up RADIUS Client Although I get the same
when I do.
My Question would be am I missing Open Ports to get same results as before
IAS install or how do i reopen these ports and why did I lose the IP
addresses in DHcp?Its weird its only 3 IP addresses im losing but all 5
ports. Any Ideas????

3. Different IAS client policy for different IAS clients

4. IAS on member server cant see "RAS and IAS Server" template listed

5. Dilema: IAS on DC or IAS on separate server?

6. IAS crashes on start... no VPN !
