SYMPTOMS
After you install Exchange 2000 Server, the performance may be lower than you expect.



CAUSE
This problem may occur if your network adapter driver is set to automatically detect network speed. The network adapter driver may set the speed to 10 megabits per second (Mbps) even if the network operates at a faster speed, and the network adapter can match it.



RESOLUTION
To resolve this problem, manually change the network adapter speed to match the network speed:
 * 1) Click Start, point to Settings, and then click Network and Dial-up Connections.
 * 2) Right-click the local area connection that corresponds to the network adapter that you want to modify, and then click Properties.
 * 3) Click the General tab, and then click Configure.
 * 4) On the Property list, click the Advanced tab, and then click NetworkMedia.
 * 5) In the Value box, click the speed that you want to use.
 * 6) Click the Full Duplex option, and then click OK.



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