Actually you have kill the Golems. They turn hostile as soon as you excgange the eggs.

Not to mention they're worth XP and killing golems is always fun! :D

What he meant was it is possible to avoid the golems. The fight is not necessary. Thank you for the help, Raistlin! It worked!

Yeah, I had some nasty times with this as well. For some reason, all the Drow turned hostile if I left my party near the to the Temple. Now, I just move my entire party right up to the Egg Vault, and everything's groovy. Whether I kill the guards first or open the door first, the city stays Neutral to me.

for me the guards didn't turn hostile when you approached them.

<span style="color: lightblue">It seems to me to be a matter of killing the egg guards before they yell "Protect the Eggs!", as that sends the city hostile. In my solo sorc game, I tried getting out of sight of the others, but they still turned hostile soon after the "Protect the Eggs!"... the easiest way I found of stopping that shout, was to kill them before opening the door.
Although the answer to this may be as computer dependant as "do summons stay summoned if you rest in another area?".

The Drow door guard bug comes into effect after installing TOB - there's a fix on Baldurdash :
