I am currently running the newest P 4.0 on a corporate network using Win XP as a guest OS including the newest patches. My trouble is the following: 1. Printing to any networked printer, e.g. an HP 2605dn, is extremely slow, roughly taking 3-4 minutes per page. I'm using "Shared Networking" as "Bridged" causes authentification errors when accessing Sharepoint within the domain. 2. Copy operations on various networked hardware, e.g. other computers, disks etc. take excessively long. This is particularly noticeable when using Sharepoint Server 2007 through the (guest) Windows Explorer to copy files. The network is a domain-based corporate network using multiple servers, Exchange 2003 and Sharepoint 2007. Anyone has a clue what might be going on?
