Windows NLB CASArray. MAPIMailbox::OpenMessage - OpenEntry (0x80040115) failed

Hello,

BES Express 5.0.3 MR 2 and Exchange 2010 three CAS server (two of them in CASArray using Microsoft NLB), Two MBX Server in DAG.

 

Every day BES lost Exchange server and we go (from MAGT log):

 

[20265] (08/22 10:09:01.647):{0x1644} {User@domain.com} MAPIMailbox:Smiley SurprisedpenMessage - OpenEntry (0x80040115) failed
[20265] (08/22 10:09:01.648):{0x1644} {User@domain.com} MAPIMailbox:Smiley SurprisedpenMessage - OpenEntry (0x80040115) failed
[20205] (08/22 10:09:01.648):{0x1644} {User@domain.com} AddRefIDProp() failed: ERR_NETWORK_PROBLEM, EntryId=168976

 

And

 

[20709] (08/22 10:19:30.665):{0x19C0} {User@domain.com} Failed to reach user's mailbox

 

I have found  Article ID: KB20066

 

Article said, that we have to switch to one dedicated CAS server instead of using CASArray.

Is there a chance to keep BES connected to CASarray (Windows NLB)?

 

Thank you

do you still get this problem? Do you update your BESX to 5.0.4 ?

Hello,

 

That was a connectivity problem, We pointed BES to the one CAS and pointed them back to the CASArray when fix the communication problem. Current configuration Exchange 2010 SP2 RU5v2 + BES Express 5.0.4
