Access Violation in Mspadmin.exe with ISA Server with Multiple IP Addresses on an External Interface (288247)
The information in this article applies to:
- Microsoft Internet Security and Acceleration Server 2000
This article was previously published under Q288247 SYMPTOMS
On computers with any of the following configurations, Internet Security and Acceleration (ISA) Server services may not start:
Number of IP addresses Problem occurs
------------------------------------------------------
1 internal and 2 external (total 3) no
1 internal and 3 external (total 4) no
1 internal and 4 external (total 5) occurs
1 internal and 5 external (total 6) no
1 internal and 6 external (total 7) no
1 internal and 7 external (total 8) occurs
1 internal and 8 external (total 9) occurs
1 internal and 9 external (total 10) no
1 internal and 10 external (total 11) occurs
You may receive one of the following error messages:
Error 1053 server control service failed to start
Error 1067 server control service process terminated unexpectedly
Event 7022 The Microsoft ISA Server Control Service hung on starting.
Event 7031 The Microsoft ISA Server Control Service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 0 milliseconds: No action.
No other configurations were tested for this problem.
This issue applies to active interfaces; if your configuration does not match the table above and the ISA Server services start but a user later creates a virtual private network (VPN) connection to the server that is running ISA Server, or if the ISA Server computer dials out with VPN or a modem, causing it to have an additional IP address, the ISA Server services may stop working.
CAUSE
The problem is initiated by the Bwserver.dll file in CreateInterface because of bad pointer math when enumerating addresses.

Date Time Version Size File name Platform
----------------------------------------------------------------------

WORKAROUND
One possible workaround is to clear the QoS Packet Scheduler check box for all interfaces in Network properties. This does not affect ISA Server bandwidth control functionality.
STATUSMicrosoft has confirmed that this is a problem in Microsoft ISA Server 2000. This problem was corrected in ISA Server 2000 Service Pack 1.
