error message

I have recently began a upgrade of all my company PC’s. I create a specifice image. Now that I have the image set and began rolling it out, whenever a user prints for the first time int the morning the get an error message stating:
“Failed to obtain Workstation License”
They click ok and all printing it fine for the remainder of the day.

I used Symantec ghost to rollout the image. Any ideas why this message comes up? Whe are using a print server so the printers are networked.

Thanks.
