Problem starting KDE 3.1 on cygwin

[Eric I. Asch]

Cygwin 3.1 just installed on Win XP.
uname: CYGWIN_NT-5.1      1.3.18(0.69/3/2)
 
KDE hangs at "starting IPC communications" with multiples of this error:
"DCOPClient::attachInternal. Attach failed Authentication Rejected,
reason : None of the authentication protocols specified are supported
and host-based authentication failed"
 
Looks like some other users get the same error, but I haven't found any
advice on how to resolve.
 
Thanks!
