Problem

“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”

Finally a search solved my problem...

Solution

In order to develop with SharePoint I use Virtual PC or Virtual Server 2005 images. Installing Windows Server 2003 takes about an hour and because of that I copy the images and change the SID using NewSID.exe. After that I get the error and using Google I found the solution at Joe unfiltered:

“I had created this VPC by copying the virtual hard disk from another VPC and running NewSID on it. I was under the impression that this fixed any issues regarding SIDs from the old machine conflicting with SIDs on the new one. Not quite, it turns out. The IIS_WPG group from the old box is on the ACL of the app pools in the metabase, not IIS_WPG of the new box. Use metaacl.vbs (download from MS) to check.”

Use the command:

MetaAcl.vbs "IIS://localhost/W3SVC/AppPools"

One of the entries will be an SID, not a user/group name. This is the IIS_WPG from the old box. To fix this, add the IIS_WPG group of the new box to the ACL in question using the command:

MetaAcl.vbs "IIS://localhost/W3SVC/AppPools" IIS_WPG U

So if your working with WSS 3 or MOSS 2007 and you use virtualization you should apply the fix.

Thanks to Joe!
