Connecting to NAS drives on initial boot

I am getting the usual problem that windows has never fixed. On boot up quite often I get the message that network drives could not connect. They are 'X'ed out, but on clicking they are really there. It used to be the random way windows boots all the drivers up. But on reboot it all seems to work. Is there any boot item that needs to be delayed to allow network card to fire up before it tries to connect to the network. This does not affect internet connection just nas drives.

I had a similar problem that went away after I disabled the NAS sleep function. I put it down to too long a delay at NAS wakeup.

Not saying this is the same as yours but may be worth looking at.

I've also seen that triangle but just on one comp but that seems to have gone away now.
