Hi,

We have 4 Exchange Server 2013 in cluster.

Every time we are getting 1177 & 1135 alert.

Hi redhat,

Thank you for your question.

You could refer to link which Andy supply.

If the issue persist, we suggest you post entire alert information which is about event id 1177 and 1135 to ibsexc@microsoft.com for our troubleshooting.

In addition, the following link is about Event ID 1133:

https://technet.microsoft.com/en-us/library/cc773498%28v=ws.10%29.aspx

if the issue persist, we could check if there are the IP address conflict error occurs when more than one node in a cluster attempts to bring a resource group (and its associated IP(s)) online at the same time. This can happen if the cluster nodes momentarily lose contact with each other. Each node assumes the other node has failed, as a result the 'passive' node will bring all resource groups online when they are in fact still online on the 'active' node.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
