Hi Friends, I am facing problem on exchange 2003 server. I had run the Extra tool on the server and found the below issue. 1)Disk bottleneck found : A potential performance issue was observed from the disk performance counters. One or more disks is exhibiting a performance bottleneck. 2 )Lightweight Directory Access Protocol (LDAP) latencies beyond threshold : The 'MSExchangeDSAccess Domain Controllers LDAP' performance counters are beyond the recommended threshold.

1: The issue is with your hardware, you need to get in touch with your hardware vendor to check the health of your hardware. Ask them to run the Hardware Diagnostics on the server and i am sure there will be few errors. http://technet.microsoft.com/en-us/library/aa995945(EXCHG.80).aspx 2: http://technet.microsoft.com/en-us/library/aa997381(EXCHG.80).aspx http://technet.microsoft.com/en-us/library/aa998149(EXCHG.80).aspx Cheers, Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

Hi 1.Disks that are accessed at a rate higher than the disk subsystem can support is one of the most common causes of disk latency. In this case, the disk is said to be a bottleneck. This also means that the disk subsystem is at or beyond its throughput capacity. My suggestion is to reduce load of the server or replace harddisk. you can also read this link http://blogs.technet.com/b/exchange/archive/2005/09/28/411674.aspx 2. It is not serious error. The server which is in different location will cause this issue. Gulab Mallah has offered you the link. It can tell you how to resolve this error.

Hi Do you have anything to update this issue ?
