owa "cannot connect to directory server" - 18.Jul.2007 8:55:02 AM

I have a client who is upgrading from exchange 2000 to 2007.

When connecting to OWA, the user cannot access the GAL, or any address list. The specific error message states "Cannot connect to directory server". The detailed error message references one of the domain controllers for the site.

The DC's are running Windows 2003 SP1 and SP2. The directory server this error message occurs on is SP1. We have patched the server with the hotfix referenced in another post on this topic to no avail.

The Exchange server is running Windows 2003 x64 SP2.

I may have to call MS on this - any help appreciated though.

uh, no. Would that it had been that easy! (I generally search the knowledge base and read up before reaching out for help, thank you...)

To perform paged searches against a DC from a .NET application like OWA, the Virtual List View (VLV) and sort controls must be available on the domain controller. In this case these were disabled and had to be re-enabled.

Note that the following procedures were only taken after much troubleshooting under the guidance of Microsoft's Exchange escalation team... wouldn't do this without a real reason if I were you, but it's worth a check if you run into the same issue yourself.

1. Click Start, click Run, type Adsiedit.msc , and then press ENTER.
2. In the ADSI Edit tool, expand the Configuration[ DomainController ]node.
3. Expand the CN=Configuration,DC= DomainName container.
4. Expand the CN=Services object.
5. Expand the CN=Windows NT object.
6. Right-click the CN=Directory Service object. Click Properties.
7. In the Attributes list, click msds-Other-Settings. Click Edit.
8. In the Value to add box, type DisableVLVSupport=0. Click Add. Note: If the
entry already exists and is set to a value of 1, simply click on the
Remove button, change the value from a 1 to a 0 and then click Add.
9. Click OK two times. Close the ADSI Edit tool.
10. Perform your search in OWA again and it should work.
