Just found that same info, in my case it apparently wants the SP3 install files (which I cleaned up afterwards). &nbsp;I'll try that tonight, thanks!

Hi Experts - I ran into some trouble last night trying to patch my Exchange 2010 servers. &nbsp;I have two setup in a DAG and the first patch went well but when I tried it a second time the update failed. &nbsp;The first install went normally with no prompts, the second is trying to find a file called exchangeserver.msi. &nbsp;I happened to have the install files on the local drive so I pointed it there but I then get an error about it not being a valid install file. &nbsp;This is incorrect, its the same .msi used to apply SP3 and is the same as what's on the server that successfully applied the update. &nbsp;So now the two servers are on slightly different versions of Exchange which I'd like to minimize. &nbsp;<br />
<br />
Any ideas on what might be the problem and how I can work around it to get this server patched?

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
