SYMPTOMS
Consider the following scenario. You have multiple global catalog servers in a Windows 2000-based forest, you cannot manually reset connections between domain controllers and global catalog servers. Therefore, responses from global catalog servers may be very slow if the connections between global catalog servers and domain controllers are not highly available. This situation may occur when the following conditions are true:
 * The global catalog servers are connected to the domain controllers by wide area network (WAN) connections.
 * The connections between global catalog servers and the domain controllers are overloaded.

In this situation, you may experience various performance issues with the Active Directory authentication. For example, the client users may wait for a long time when they are logging on to the domain.



RESOLUTION
This hotfix enables you to manually reset connections between global catalog servers and domain controllers. After you apply this hotfix on the domain controllers, you can manually reset the connections between global catalog servers and domain controllers. Then the cache in the domain controllers is flushed. To do this, set the invalidateGCConnection attribute of the rootDSE object to a value of 1 by using the Active Directory Service Interfaces (ADSI). To do this, follow these steps:   Paste the following script to a text file. Then, save the text file by using the name of Resetgc.vbs. ' check the parameters Set oArgs = WScript.Arguments If oArgs.Count <> 3 Then WScript.Echo &quot;Wrong number of arguments&quot; WScript.Echo &quot;Usage: cscript resetgc.vbs servername domainname\username password&quot; WScript.Quit(1) End If ' Execute the command Set LDAPNameSpace = GetObject( &quot;LDAP:&quot; ) Set Root= LDAPNameSpace.OpenDSObject( &quot;LDAP://&quot; & oArgs(0) & &quot;/RootDSE&quot;, oArgs(1), oArgs(2), ADS_SECURE_AUTHENTICATION ) Root.Put &quot;invalidateGCConnection&quot;, &quot;1&quot; Root.SetInfo WScript.Echo &quot;The global catalog connection on &quot; & oArgs(0) & &quot; has been invalidated.&quot;  Open a command prompt, and then move to the path where you saved the Resetgc.vbs file in step1. Run the following command at the command prompt:

cscript resetgc.vbs  \

Note  is the computer name of the domain controller. is the name of the domain. is the username of a domain administrator. is the password for the user name that you specified.
