Delay explorer timeout for network shares

[FiB3R]

My new PC boots up so fast, that I'm on the desktop before the network has had a chance to fully initialise. (Win8.1 x64)

So any network share folders I have kept open from a previous session, throw an error.

 

I can click Diagnose and then Cancel. This at least stops the folder from closing, but it's a pain in the harris. #firstworldproblems

 

So, is there a way increase the amount of time it gives me, before thinking that the folder is missing?

 

Thanks.
