   By default, SQL Server will use all available memory. But if the server   
   is not dedicated for SQL Server (as in your situation), then this can   
   cause memory to be paged out to disk, causes serious performance   
   problems.   
      
   So you should check the memory settings (SQL Server Enterprise Manager,   
   request Properties of the server, go to tab Memory), and set the maximum   
   memory to considerably less than 1.7 GB. For starters, set the max to 1   
   GB. After a few days, check what the available memory is (memory still   
   available to Windows). If it is less than 30 MB, then lower the max. If   
   it is more than 100 MB, then increase the max.   
      
   Good luck,
