To help promote the seperation of duties one of the things my company has done is to divide our permissions into two accounts. We have one account that is for our daily tasks. Reading email, searching the internet, basic structure changes in a database etc. The other account is our admin account. It’s for remoting to servers, security tasks, really anything that requires sysadmin. I’m not going to argue the advisability of this because honestly, I’m kind of on the fence. That said, I do have to deal with it and there are a few tips in case you have to deal with it as well.
And if you’re not on the domain as well,
runas /netonly /user:[domain\username] ssms.exe will do the job.
