SYMPTOMS
Microsoft has identified a bug in the recent MS03-32
Security Update for Internet Explorer security patch when you apply the patch
on a computer that is running Microsoft Windows XP and has Microsoft ASP.NET
1.0 installed. This patch can be installed manually or by obtaining recent
critical updates from the Windows Update Web site.
After you install
the patch, you receive the following error message when any request is made to
ASP.NET:
Server Application Unavailable
This bug
affects only computers that are running ASP.NET 1.0 on Windows XP. It does not
affect computers that are running Microsoft Windows 2000 or Microsoft Windows
Server 2003. This bug also does not affect computers that are running Windows
XP and have ASP.NET 1.1 installed.
The following table lists the
operating systems and the versions of the Microsoft .NET Framework that are
affected by this bug:
|
| 1.0 | Windows 2000 Professional | No |
| 1.0 | Windows 2000 Server | No |
| 1.0 | Windows XP Professional | Yes |
| 1.0 | Windows Server 2003 | No |
| 1.1 | Windows 2000 Professional | No |
| 1.1 | Windows 2000 Server | No |
| 1.1 | Windows XP Professional | No |
| 1.1 | Windows Server 2003 | No |
WORKAROUND
To work around this bug, run the batch file that is
described in the "Batch File" section of this article. This batch file does the
following:
- Stops the IIS and the ASP.NET state services.
- Deletes and then re-creates the ASPNET account by using a
known temporary password.
- Uses the Windows runas command to start an executable that creates an ASPNET user
profile. An ASPNET user profile works around the issue.
- Reregisters ASP.NET. This step creates a new random
password for the account and applies default ASP.NET access control settings
for the account.
- Restarts the Microsoft Internet Information Services (IIS)
service.
The batch file contains a hard-coded temporary password of
"1pass@word". You will be prompted to enter this password for the
runas command when the batch file runs. After the
runas command has completed, the ASPNET account password is re-created
by using a strong random value.
Important Notes
- The batch file may fail if the hard-coded password does
not meet the password complexity requirements in your environment. If this
problem occurs, you can change the password to another value that is
appropriate for your environment.
- If you have added custom access control settings or
database account permissions for the ASPNET account, you must re-create these
settings or permissions after this batch file has completed. This is because a
new security identifier (SID) is assigned to this account when the account is
re-created.
- If you are running the ASP.NET worker process by using a
custom account that is different from the ASPNET account, do not run this batch
file. Instead, you must log on to the computer interactively or you must use
the runas command with that custom account. This procedure creates a user
profile for the custom account.
To use the batch file, follow these steps.
Note Your account must be a member of the Administrators group.
- Start Notepad. Verify that Word Wrap is
turned off.
- Paste the batch file code in Notepad.
- Save the file as
c:\fixup.cmd.
- Click Start, and then click
Run.
- Type cmd.exe, and then press
ENTER.
- At the command prompt, type
c:\fixup.cmd, and then press ENTER.
- When you are prompted for a password, type
1pass@word.
A second command prompt window
appears. - After you apply the patch, type exit
in the second command prompt window, and then press ENTER.
- If you previously configured custom access control settings
or database account permissions for the ASPNET account, you must now reapply
these settings.
