SYMPTOMS
After you install McAfee VirusScan Professional 7.0 from Network Associates, and then you restart your computer, several Microsoft Windows services may not start as expected, and your computer may be generally unresponsive. When you open Task Manager to view the processes that are running, you see that the Msdtc.exe process is at 99-percent CPU utilization. If you disable McAfee VirusScan, this problem is not resolved.



CAUSE
This problem may occur if you install McAfee VirusScan Professional 7.0 on a Microsoft Windows 2000 Server-based computer. In this scenario, there may be a conflict that is caused by the VirusScan drivers and by the VirusScan registry settings.



RESOLUTION
To resolve this problem, follow these steps:
 * 1) Restart your computer, and then when the start menu appears, press F8.
 * 2) When the Windows 2000 Advanced Options Menu appears, select Safe Mode, and then press ENTER.
 * 3) After you log on to your computer, click Start, point to Programs, point to Administrative Tools, and then click Services.
 * 4) Click Distributed Transaction Coordinator (MSDTC), and then in the Startup type list, click Disabled.
 * 5) Restart your computer, and permit it to start in the standard way.
 * 6) Click Start, point to Settings, point to Control Panel, and then click Add/Remove Programs. Click McAfee VirusScan Professional 7.0, and then click Remove.
 * 7) After McAfee is completely removed (uninstalled), click Start, point to Programs, point to Administrative Tools, and then click Services.
 * 8) Click Distributed Transaction Coordinator, click Automatic in the Startup type list, click Apply, click Start, and then click OK.
 * 9) Use Task Manager to verify that the MSDTC service (Msdtc.exe) is no longer using all your CPU resources.

Note If you tried to manually remove the McAfee program by deleting files and registry entries, and you are still experiencing the problem, disable the MSDTC service (steps 1 through 5), reinstall McAfee VirusScan Professional 7.0, restart your computer, and then remove McAfee VirusScan by using the Add/Remove Programs tool in Control Panel. After the program removal operation, restart your computer, and then re-enable the MSDTC service.
