Change IP Address on BizTalk Server
Change IP Address of the BizTalk boxes is supported except below senarios:
1, If the server has the MSMQ adapter, in which case the server needs to be reinstalled(http://support.microsoft.com/kb/836487)
2, If you are using IP Addresses anywhere in your configuration instead of of server names (eg.remote host IP) , then you have to export all of your bindings in the server and make sure you are not pointing back to the server itself somehow.
3, During installations period, sometimes the entire system run with IP Addresses instead of host names (MS DTC with no authentication). Check it in your BizTalk Configuration Tool, on the View Menu select Databases and review the database server list to make sure they are all using Server names not IP Addresses. Then in the Configuration tool, select each node and make sure nothing is using IP Addresses.
