We had a small 3 workstation workgroup running windows 98, which was used to run a DOS based database application.<br />
<br />
We have just replaced the 3 workstations with new XP based systems. The local server runs the database just fine, but the two networked workstations run really slowly.<br />
<br />
We have identified that ntvdm.exe is takeing 100% of the CPU bandwidth while ever the database is open on the networked computers, which causes them to run really slowly. I understand that this program is the 16bit virtual machine, used to run a 16 bit application in a 32bit environment, but we need to resolve this, as the workstations become un-usable whenever the database is open.<br />
<br />
Can anyone help in resolving this issue?<br />

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

Microsoft Legacy OS

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
