SYMPTOMS
After you install Microsoft Internet Security and Acceleration (ISA) Server 2004 on a multiprocessor computer, and then you restart the computer, you experience both of the following symptoms:
- The following services do not start as expected:
ISACTRL
WSPSRV The following event is logged in the System log:
Event Type: Error
Event Source: Microsoft ISA Server Control
Event Category: None
Event ID: 14109
Date:date
Time:time
User: N/A
Computer:computer name
Description: The ISA Server Standard Edition cannot run. Either the server is using more than 4 processors, or it is configured to use the Active Directory service. Use the source location 100.281.4.0.2161.50 to report the failure. Contact Microsoft (R) Corporation for more information.
The computer on which you installed ISA Server 2004 does not have more than four processors.
CAUSE
This problem occurs if the following conditions are true:
- The computer that you install ISA Server on has more than two processors.
- Hyper-Threading Technology (HT) is enabled on this computer.
- The processors are multicore-packaged.
This problem occurs because ISA Server 2004 incorrectly determines the number of processors that are installed in a computer when Hyper-Threading Technology is enabled or when the processors are multicore-packaged. ISA Server 2004, Standard Edition supports up to four processors. However, if you have Hyper-Threading Technology enabled, or if the processors are multicore-packaged, ISA Server 2004 incorrectly calculates the number of processors.
RESOLUTION
Service pack information
To resolve this problem, obtain the latest service pack for ISA Server 2004. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
891024 How to obtain the latest ISA Server 2004 service pack
WORKAROUND
To work around this problem, disable Hyper-Threading Technology on the ISA Server 2004 computer. If disabling this technology does not resolve the problem, install the latest ISA Server 2004 service pack.
Note If you install ISA Server 2004 on a server that is running Microsoft Windows 2000 Server, ISA Server cannot correctly determine the number of logical processors.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in ISA Server 2004 Service Pack 1.
