I'm using WDS/Server 2008 R2 to deploy Windows 7 in a small organization. I have WDS configured to respond to all PXE clients, but require administrator approval.
When I PXE-boot a client, it sees the WDS server and begins to boot, then pauses awaiting for the admin approval. On the WDS server, the machine shows up as 'pending approval'. Everything as you;d expect.
The problem comes when approving the client request. If I pick either 'Approve' or 'Name and Approve', then WDS gives an error "The parameter was not correct".
If I configure the server to respond and automatically accept all requests, then everything works.
I can't find anything in the Internet about this issue, so over to you guys.... any ideas?
