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

-or-

Error 1067 server control service process terminated unexpectedly

-or-

Event 7022 The Microsoft ISA Server Control Service hung on starting.

-or-

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.



RESOLUTION
A supported hotfix is now available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.

The English version of this fix should have the following file attributes or later:   Date       Time       Version      Size         File name     Platform --  3/11/2001  3:37:22PM  3.0.1200.55  29,968Bytes  Bwserver.dll  Intel



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.



STATUS
Microsoft has confirmed that this is a problem in Microsoft ISA Server 2000. This problem was corrected in ISA Server 2000 Service Pack 1.



MORE INFORMATION
After you apply this hotfix, three redundant values may be added into the Registry, which will need to be fixed in order for IIS to work properly. For more information, refer to the following article in the Microsoft Knowledge Base:
