SBS 2011 Exchange Error - Could not read the Security Descriptor from the Exchange Server object with

This can occur when an old Exchange server (such as one on an SBS 2003 server) was not properly uninstalled to clean up AD. The result is an orphaned object. The error is a transient one and can be ignored, or if you are daring, you can use ADSIEdit and try to prune the data. There are documented procedures on how to do so on technet, but it isn't for the feint of heart, and it isn't something I'm personally comfortable recommending or trying to assist someone do via EE. But at least this answer will hopefully give you an idea WHY you have the error and what your options are.

Good luck,

THanks for the response I thought it might be something like that, however I am also seeing some other worrying alerts in the event viewer

Do you think these are related?
 

Possibly. It also sounds like perhaps your sites and their IP ranges are incorrectly defined in "Active Directory Sites and Services" ....but those errors are again, not particularly significant. Exchange is letting you know that it thinks it is contacting a server at another site (which if you pay for WAN links per megabit would be a big deal) so it throws the warning. If the machines are in fact local then the warning is inaccurate, but not an indication of a component failing.
