Many times (not always) when my users log in, they get the following
error
message.

"A required .DLL file, F:\CLNTRUST.EXE, was not found"

I'm running BM3.7 on NW5.1SP6. My workstations are Win98 wit Client
3.32SP2.

The users login scripts are:
MAP ERRORS OFF
MAP ROOT F:=.CUS1_SYS.MS.CHESANING:PUBLIC
MAP ROOT H:=.CUS1_USERS.MS.CHESANING:2007\%login_name
MAP ROOT P:=.CUS1_VOL1.MS.CHESANING:APPS
MAP ROOT V:=.CUS1_VOL1.MS.CHESANING:APPS\VS6
MAP ROOT O:=.CUS1_VOL1.MS.CHESANING:OFFDATA
IF MEMBER OF ".STUSHARE.HS.CHESANING" THEN
MAP ROOT T:=.CUS1_VOL1.MS.CHESANING:STUSHARE
END
MAP INS S1:=.CUS1_SYS.MS.CHESANING:PUBLIC\
MAP INS S2:=.CUS1_SYS.MS.CHESANING:PUBLIC\WIN32\
#F:\policy850.exe
@F:\dwntrust.exe
@F:\clntrust.exe
WRITE "Launching NAL Explorer ..."
WRITE ""
@F:\NalExpLd.exe

Users have been explicitly assigned read and file scan rights to the
public
directory on the server they are mapping F to.

Any ideas what might be causing this error?

Thanks,

Brad
