HTTP 500 Internal Server Error when accessing SCCM Reports

If you are receiving HTTP 500 Internal Server Error when accessing SCCM Reports via web browser, check the following settings:

1. Make sure that you are not hitting the limit of maximum rows returned by a report query. By default, report viewer in SCCM 2007 is configured to limit the results returned by a report query to 10 000 rows.

To change the number of rows returned by a report query, create the Rowcount DWORD value under the HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\Reporting registry key.

Set its value to the number of rows that you want returned in the report query. If you want to return all rows, set the value to 0xffffffff, which is the hexadecimal equivalent of –1.

For more information, refer to the following TechNet article: How to Configure the Maximum Rows Returned by a Report Query, available at the: http://technet.microsoft.com/en-us/library/bb680885.aspx

     

2. Increase the ASP response buffer limit size (aspbufferinglimit).

In IIS 6.0 change has been introduced which limits a default ASP response buffer to 4 MB. Increasing the buffer limit might help you in resolving this problem. To increase the buffer limit, follow these steps:

  • Click Start, click Run, type cmd, and then click OK.
  • Type the following command, and then press ENTER:

cd /d %systemdrive%\inetpub\adminscripts

  • Type the following command, and then press ENTER:

cscript.exe adsutil.vbs SET w3svc/aspbufferinglimit LimitSize

LimitSize represents the buffering limit size in bytes. For example, the number 67108864 sets the buffering limit size to 64 MB.

To confirm that the buffer limit is set correctly, follow these steps:

  •   Click Start, click Run, type cmd, and then click OK.
  • Type the following command, and then press ENTER:

cd /d %systemdrive%\inetpub\adminscripts

  • Type the following command, and then press ENTER:

cscript.exe adsutil.vbs GET w3svc/aspbufferinglimit

In my case, setting the limit to the value of 12582912 (12 MB) did the trick in the Configuration Manager environment of approximately 10 000 managed devices (SCCM Clients).

For more information about the ASP response buffer limit, refer to the following article: Error message when a Web browser sends a request for an active server page to a Web server that is running IIS 6.0: “Response buffer limit exceeded”, available at the: http://support.microsoft.com/kb/925764
