I would like to move my pagefile.sys from my c: to my d: on SBS 2008 what is the best way for me to do this
You can use the standard System Properties > Performance Options to move the Pagefile, but make sure that SYSTEM has full control on D:.
More detailed instructions:
Right-click Computer > Advanced system settings > Advanced tab > click Settings... under Performance > Advanced tab then Change button.
Creating a new page file on your D: volume and removing the pagefile from C: should be safe. The limitation of older Windows versions where no kernel or complete memory dumps could be created whenever there was no sufficiently sized page file on the boot volume has been removed with Windows Server 2008 - you can use the DedicatedDumpFile option to configure a dump file location on any of your volumes.
