AFS Client for NT
Enables access to files in the worldwide
AFS filespace from NT workstations
 Supports Windows Explorer for
browsing files
 Version - AFS 3.4a Patch 9.3
 Several problems reported to Transarc
have been resolved

Installation - AFS Client for NT
Easily installable - Setup interface
 Requires ~ 6Mb on system disk and at
least 16 Mb of RAM
 Recommend increasing the pagefile by
50 Mb
 Most files go into
\Program Files\Transarc\AFS\AFSClient
 Adds Transarc program dir to path

Configuration - AFS Client
AFS filespace is referred to by
\\hostname-afs\all
 Can define submounts of the form
\\hostname-afs\userid
 Control panel interface for config
 Shell extensions (right-click) AFS menu
for AFS files (Auth, ACL’s, etc…)

Authentication
Logging in to NT also authenticates
user on AFS (if NT and AFS userid and
password are identical)
 In the default configuration this gives
tokens valid for 25 hours
 Unlock screen does not refresh AFS
tokens - This can produce confusing
error messages/results

Implementation on NICE NT
