Activesync advanced monitor failing after Exchange 2013 CU2 update

Hi Guys

 

 

I've got 2 sets of exchange 2013 servers. On one set I've recently applied CU2 and it looks to have caused a problem with the advanced monitor.

 

 

The monitor is sending the following string

 

GET /Microsoft-Server-ActiveSync/ HTTP/1.1\r\nHost: mail.domain.com\r\n

 

and expecting the response

 

Supported

 

In the IIS log I see the following from the advanced monitor request.

 

2013-07-17 19:56:10 172.23.152.21 GET /Microsoft-Server-ActiveSync/default.eas &cafeReqId=32e1b601-d4cb-4d39-9109-4dbe6004ae4a; 443 domain.com\f5.monitor 172.23.152.101 - - 500 0 0 20014

 

 

The standard monitor is recieving the correct response and if I remove the advanced monitor and replace it with a standard https one the pool member is fine.

 

The other set of Exchange 2013 CU1 servers are fine so I'm very sure its a problem introduced by CU2.

 

 

Anyone else experienced this and know a way to fix the monitor? it doesn't seem to have affected any of the other advanced monitors for other exchange web apps.
