Re-Imaging with OSD

[twisd25108]

I currently have SCCM SP2 R2 on a Windows 2003 x64 Enterprise server with OSD up and running. We are currently working on getting things ready to roll out Windows 7 for the next year, and I have been able to successfully apply a Windows 7 Image to an unknown computer and a known computer, but once the computer finish's setting up and the ConfigMgr client as initialized during the setup, I can't image for another 30 minutes or so. When I look at the SMSPXE log it states that theres no advertisement though I have it advertised to All Systems and All Unknown Computers as it obviously worked the first time for both unknown and known. Is this just because SCCM is in the process of updating the client's records in the DB or something of that sort? I'm currently using the OSDComputerName script which allows me to rename the computer while booted into the WinPE boot image. I originally had it always asking me for a name, but I've amended it to the original script which checks the database for a name and only prompts if SCCM doesn't currently have it in the database. I haven't had a chance to test it since doing that, should that solve my issue? Thanks for any and all help.
