   tempdb.mdf is recreated every time you restart SQL Server. But I guess   
   it reuses the existing file. If you remove the file, the file has to   
   be initiated; I don't think there ever is Instant File Initialisation   
   on SQL 2000. Zeroing out 200 GB takes some time.   
      
   What do you see in the SQL Server errorlog?   
      
   Why you tempdb file is so big I cannot say, since I don't know your   
   system, but tempdb is used for more than just temp tables, for instance   
   work tables for queries, and spill area for sorting and hashing. Bad   
   queries can cause your tempdb to grow.   
      
   Exactly which command did you run to change the size of tempdb?
