Although I use NT at work I am not an expert as it is locked down to stop me playing with it but I found this:
DLL File: crtdll or crtdll.dll DLL Name: Microsoft C Runtime Library Description: Contains Standard C Library Functions such as printf, memcpy and cos System DLL: No
Common Errors: File Not Found, Missing File, Exception Errors Solution: Many problems can be solved by resinstalling this application. If the DLL is missing, download it to your windows system folder.
The dll can be downloaded from click here but you may need a boot floppy to get it on your system. I've got the horrible feeling that I've read somewhere that NT doesn't boot from a floppy and I hope I'm wrong but an NT expert on here should hopefully be able to advise you.
Your helpdesk sound just like ours.
