Problem: IIS 6.0 / Server 2003 Event Log Entry: "Unable to get the private bytes memory limit for the W3WP process. The ASP.NET cache will be unable to limit its memory use, which may lead to a process restart. Error 0x80070005". 

 

Solution: There is a known issue with insufficient permissions to your IIS metabase; the ACL doesn’t include the IIS_WPG group.. They have published a tool which allows you to change the permission.

 

Download the utility from http://support.microsoft.com/?id=267904 and run this from a command prompt:

 

cscript metaacl.vbs IIS://Localhost/W3SVC/AppPools IIS_WPG RE

 

Here is a reference to the blog from Microsoft detailing this problem and it’s resolution.
