If you create a pagefile on different volume, you may receive the following message when you restart:
Limited Virtual Memory. Your system is running without a properly sized paging file. Please use the virtual memory option of the System applet in the Control Panel to create a paging file, or to increase the initial size of your paging file.
When you check in Control Panel / System / Performance / Virtual Memory / Change, the correct values are listed. When you run Windows NT Diagnostics, WinMSD.exe, the Memory tab shows that the new pagefile is pointing to a temporary pagefile.
Check to insure that the SYSTEM account have FULL CONTROL on the drive root.
