I look after a small network of around 100 client PC's and 3 Windows 2003 servers. The version of windows are as follows..
SIMS and SQL Server 2005 = Server 2003 R2 - Standard Edition - Service Pack 1
Terminal Server and AD = Server 2003 R2 - Standard x64 Edition - Service Pack 2
Exchange 2003, Sophos and AD = Server 2003 R2 - Standard Edition - Service Pack 1
I have an upgrade to the Sophos Pure Message that is on the Exchange Server and it requires Service Pack 2. So my question is.. is it safe to upgrade to Service Pack 2 on that server? I am very nervous about messing up Exchange in any way. Also the SIMS server could do with Service Pack 2 as well.. what do you think?
Also the automatic windows updates fail on the servers as we are behind a proxy. Is it safe to run Windows Updates once to let them catch up on Security Patches and stuff? I really don't want to corrupt anything.. or change the way somethings work.
Any help and advice would be most welcome.
Thanks in advance.
