SYMPTOMS
On a computer that is running both Microsoft Windows 2000 and Microsoft Windows XP, you are unable to open Phone Dialer.



CAUSE
This problem occurs because one Dialer.exe program overwrites the other Dialer.exe program on a computer on which you have installed at least one instance of both Windows 2000 and Windows XP on the same system drive.

WARNING: Microsoft does not support loading more than one operating system in the same partition in a multiboot scenario, as erratic behavior can ensue.



RESOLUTION
To work around this behavior, do not install Windows XP onto the same system drive as Windows 2000.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
Phone Dialer in Microsoft Windows XP is significantly different from Phone Dialer in Microsoft Windows 2000, Microsoft Windows 2000 Datacenter, and Microsoft Windows 2000 Service Pack 1 (SP1). In Windows XP, Dialer.exe is located in the %SystemDrive%\Program Files\Windows NT folder.

For more information about Phone Dialer in either Windows 2000 or Windows XP, refer to Help.

IMPORTANT: Microsoft does not support the installation of more than one operating system in the same partition, in a multi-boot scenario.
