Alex asked me about this on Friday, I checked his principal and it had rc4 and 3des but not DES. And it's not a cluster machine so it shouldn't be reactivate. Could be a one-off but I was hoping someone could verify other beta workstations (specifically, -workstation )were not affected. I'm out of town and can't test.
