SYMPTOMS
When you start a program in Microsoft Windows Server 2003 or in Microsoft Windows XP, the program may run very slowly if the following conditions are true:
  • You start a program that does not have a Start in property.
  • The network connection to the mapped network share that contains your home folder is slow.
Additionally, when you log on to the computer, the logon process may be slower than expected if the following conditions are true:
  • The client computer must look for system DLL files in your home folder.
  • The network connection to the mapped network share that contains your home folder is slow.

306850 Programs start slowly or slow logon if the network connection to your home folder is slow
CAUSE
This problem occurs because the program is slowed by a high-latency connection. A program that does not have a Start in property searches for DLL files in the current working folder first, and then the folders that are specified in the system path. The current working folder is typically your home folder. If your home folder is on a mapped network share and if the network connection to that share is a high-latency connection such as a wide area network (WAN) or a virtual private network (VPN), you may experience slow performance.

Technical support for Windows x64 editions

Your hardware manufacturer provides technical support and assistance for Microsoft Windows x64 editions. Your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
