While attempting to use the 64-bit version of LoadGen<\/a> for some Exchange 2010 testing, I found the tests were failing, and in the LoadGenSim logs were lots of errors like this one:<\/p>\n

Microsoft.Mapi.MapiExceptionNetworkError: MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80040115, ec=-2147221227)<\/code>
\n<\/p>\n

I then noticed that, just above these errors, I had a line which started as follows:<\/p>\n

Outlook2003Online Error: 0 : 10\/21\/2010 15:20:53 -- Diagnostic context (user: 'DOMAIN\\CED40A97-LGU000001'):
\ndistinguishedName 'CN=CHGVA-EXM11 CED40A97-LGU000001,OU=DBTest2010,OU=2010SERVER,OU=Users,OU=LoadGen Objects,DC=mydomain,DC=com', exchServerDn '\/o=Organisation\/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)\/cn=Configuration\/cn=Servers\/cn=casserver.mydomain.com<\/code><\/p>\n

The interesting thing was that the specified exchServerDn does not actually exist. The name casserver.mydomain.com<\/em> was one I had registered in the DNS for the CAS NLB cluster, and there is definitely no server object of that name under the Configuration branch.<\/p>\n

As well as creating the NLB cluster I had also defined a CAS Array<\/a>, and the mail databases had been created after that, meaning they had the array configured in their RpcClientAccessServer<\/em> setting. Before I could get LoadGen to work I had to reset this setting on my test databases so they specified one particular CAS server, rather than the array.<\/p>\n

set-mailboxdatabase DBTest2010 -RpcClientAccessServer PHYSICAL_CAS.mydomain.com<\/code><\/p>\n

A couple of other observations..<\/h3>\n
    \n
  • Despite lots of errors in the logs about public folders and free-busy (even if you don’t select “Initialize Public Folder Database”) it seems to work fine without a PF DB on 2010 (and it won’t use one on 2007).<\/li>\n
  • The “Initialize mailboxes” step takes ages to get going. Let it run.<\/li>\n
  • I installed it on a regular Windows 2008R2 server – not an Exchange server.<\/li>\n
  • I don’t know if I’m doing something wrong, but I seem to have let each new test create its own accounts. If I try and use the accounts from a previous test it tells me I didn’t select any mailusers.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
