I have tried to solve this myself, have looked at Apple forums, honest.

It seems a long time ago I installed 2 more Macs here but it's probably only weeks. At that time I got into a muddle with Accounts but this was solved at a stroke with a tip from a Mod here (the tip was to create accounts on every computer which are identical = instant networking around the office).

However, a vestige of my muddle remains, viz:

On this computer, called W........, when I network to one other named D........, this one automatically puts in to the Connect to Server dialogue box, a username which I have deleted, at both ends.

The only way round it is to overtype it with the account name which exists at both ends.

How to get rid of an old dead deleted username which automatically hogs the Connect to Server dialogue box but is overtypeable?

I've checked Deleted Users at both ends, and deleted all deleted users......... confused It's not a big deal, just a tad irritating.

I hope I've said enough. I'd supply a screen-shot but this forum doesn't host images.

Thanks
