What level are you? This doesn't have to be done until you are finished everything else and ready to head to the Hall of Echoes.
I didn't have any problems in the ministry as a warrior in the original release of D2:ED, though that was one of the last things I did before heading to the Hall of Echoes (I did try at a lower level, and gave up, not being in the mood to listen to Zandalor's complaints about having to restart; if I muted the volume I probably could have refined my technique and done better). As mentioned above, I used a bow to help get opponents to target me rather than Zandalor (the best bow in the fjords can be bought from the smith inside the harbour building).
Rush Attack should help take out memory eaters from the back rift, while Whirlwind is handy if too many of the opponents from the front rifts get close.
If you want to try ranger skills, lack of dexterity may not be a problem. Playing a ranger on nightmare, I stopped distributing stat points on level 15, and made it to the end of the game (at the end of the Hall of Echoes, I had 36 dexterity, with equipment bonuses bringing that up to 51).
Explosive Arrow damage is based only on the skill, so any bow will do. Splitting Arrows do damage based on the bow, and at close range will pretty much one hit kill any common opponent. Poison Arrows could also be helpful, since they slow down opponents a bit and do damage. Stun Arrows might be helpful if a lot of opponents come at once, but are more intended to follow up with ranged attacks.
At least some magic spells get a bonus from intelligence in DKS (I only checked Magic Missile and Fireball; the opponent I tested on was immune to Firewall). If you want to try some mage skills, though, they may still be effective enough to help, even if they would not be as effective as they could be with a higher intelligence. Duel wielding a couple weapons with high level magic damage enchantments would help magical attacks more than intelligence, anyway.
If you have any jewellery with skill bonuses, they could help. One with a Summon Demon bonus, for example, would only need to be equipped long enough to summon, and you could swap back to your main jewellery piece.
Temporary boost potions could help a bit. Deodatus keeps casting the warrior boost spell on you, which will deactivate the Way of the Ranger or Way of the Battle Mage skills. I didn't use Way of the Ranger until I hit level 40 in FoV, and bought a bow with that skill bonus.
