We have a strange problem with one of our MOSS 2007 SharePoint installations.
When you use the people picker to find IDs in our Active Directory, it does not resolve them all!
In one instance we created a new ID in AD, and SharePoint immediately saw it (we could resolve the ID using the people picker function) but when we went back to AD and created a new ID the same identical way, SharePoint couldn't see the new ID!
One of our other SharePoint farms resolve both IDs just fine, it is just this one that is having problems. One difference between the two farms is that they are sitting in different Domains, so we are looking at anything that's different in how the Sharepoint servers are connected to the Domains...
If anyone has seen similar problems with their SharePoint installations, I'd love to hear about it!
