Hello, I am hoping someone can shed some light on this. I run the get-logonstatistics and get the output from some remote clients and the latency is high. Latency : 102431 What is the value represented as? Milliseconds? Also we have outlookanywhere set to use Basic Authentication and this user is constantly getting prompted for a password in Outlook during the day. Is this a result of this setting? I know the Outlook question is beyond the scope of the forum, but thought I could at least verify that they are related. Thanks in advance, Bphilly

Good question, I've never seen any documentation that says for sure but it can't be that hard to figure out with a quick test. 102431 milliseconds would be102.43100 seconds, so 1 minute and 42 seconds If for some reason it is using microseconds, then it would be 0.102431 seconds which is really fast. So would you say the latency is really good, or really bad? lol it seems like it has to be one of the too.

I have never seen it documented either. I dig some digging when I saw the question yesterday and could find nothing definitive from Microsoft on it. I'm assuming it is in milliseconds because that his how PerfMon reports latency. I believe that the latency measures the latency that a particular RPC client is experiencing between the client and the server and 102 seconds (102431ms) is WAY WAY WAY too much. Outlook starts to get unhappy at 200ms. I don't have an E2K7 server right in front of me, but I'm thinking that a healthy client latency would be around 5ms to 25ms.

Hi, The latency should be measured in Milliseconds. I run get-logonstatistics command on my Exchange Server 2007 Mailbox server, and I got each latency less than 100 milliseconds. However, according to the documentation, the maximum value of the RPC Averaged Latency performance counter should be less than 50 milliseconds at all times. In your situation, the latency: 102431 indicate a performance issue with one of the servers or a problem with the network, so the constantly prompted password issue should be related to this factor. Meanwhile, you can run Perfmon to monitor the RPC Averaged Latency on MSExchangeIS container on Exchange Mailbox Server. you also can run EXBPA to check healthy of your Exchange Server Below are some articles which may help for you.
