loadgen problem with ex2k3
hello,we are testing how our products affect the exchange performance and etc.have some problems with configuring exchange/loadgen for testing performance on ex2k31. There is a box('A') that has SBS2003 or W2k3(x86) with installed Ex2k3 with DC and DNS server.2. We have another machine(x64) (say 'B') that has exchange management tools sp2 installed and configured loadgen to test our product and exchange 2k3 performance on the 'A' machine.3. Machine 'B' is in the same domain with machine 'A'.4. Exchange on machine 'A' was turned to Native mode.5. If we create users/mailboxes in machine 'A' we can successfully observe them in the console in machine 'B'.Questions:1. machine 'B', Exchange Management Console: i see that 'Organization Configuration' and 'Server Configuration' folders shows messages: 'There are no items to show in this view.' or 'Your exchange organization has no servers with the Mailbox server role installed'But 'Recipient Configuration' looks good, at least i can observe mailboxes and contacts.IS IT OK?:)2. I noticed that there are 2 Administrative Groups in Exchange System Manager on machine 'A': Exchange Administrative Group and First Administrative Group.3.after configuring loadgen, initialization completed with fail and writes that some users were uninitializedand writes following in the log:RecipientBuilder Error: 0 : 04.02.2009 4:09:17 -- Unable to read serialNumber of server WHITEPONY:System.ArgumentOutOfRangeException: Length cannot be less than zero.Parameter name: length at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy) at Microsoft.Exchange.Swordfish.Extensions.RecipientBuilder.Topology.FindDirectoryObject(String[] attributesToLoad, DirectoryObjectBase parent, TopologyObjectType objectType, Topology topology, String filter, String dc, String baseDn, String directoryUsername, String directoryPassword)4.if simulation is started after that it shows message:System.ArgumentNullException:Value cannot be null.Parameter name: categoryName and etc..i can somehow attach the screenshot.any ideas why does it appear and how to fix it?

Have you installed any other versions of loadgen or load sim? If so completely remove those installations and try again.

Have you already read the online documentation of LoadGen http://technet.microsoft.com/en-us/library/bb508893.aspx? Page 444 to 469 also explains configuring and using LoadGen. http://www.amazon.com/Designing-Storage-Exchange-Digital-Technologies/dp/1555583083
