We tested UWIN version 4.5 and 5.0 on a Windows 7 (Enterprise) PC running SP1 and Novell Client 2 (SP1) and found that neither version of UWIN can access files stored on our Novell fileserver (running Netware v6.5). An "ls -al" of a folder located on a mapped network drive reports 0 (zero) as the size of all files. Copying such a file (using KSH) from the Novell mapped network drive creates a zero size file under UWIN's /home folder. However, Windows' 7 native file manager (Windows Explorer) is able to successfully copy the same file. We also tested UWIN v5.0 on a Windows XP PC running SP3 and Novell Client 4.91 (SP3) and were able to successfully copy a file (using KSH) from the Novell mapped network drive to /home. However, Perl (2009-12-18) seems incompatible with UWIN 5.0 (it won't install as a UWIN 4.x install directory is not present in the PC's registry). When will an updated version of PERL, which is compatible with UWIN 5, be made available? Under Windows 7, we then tried running KSH in Windows compatibility mode (as XP with SP3 and as Administrator) as a possible solution. This did not solve the problem and made KSH highly unstable (KSH would close/exit for no reason). We even tried running the UWIN Master Service (UMS.EXE) in XP (SP3) compatibility mode. Again, this did not solve our problem. We tried running UWIN v4.5 in Windows XP mode v1.3.76 (Windows Virtual PC) on our Windows 7 (Enterprise) machine and were able to successfully copy files off our Novell fileserver in KSH. We also tested UWIN v4.5 in VMware Player and again had no problems accessing our Novell fileserver. To date, the only issue we have running UWIN in a virtual XP environment (besides performance/speed issues) is that Perl scripts do not work. Running a Perl script exits with "Cannot execute [unknown error 14001]". UWIN's (v5.0) inability to "see" Novell mapped network drives in Windows 7 is a major problem for us. We have developed 1000's of lines of KSH scripting in Windows XP (UWIN 4.5) to "automate" climate change research, which we cannot migrate to Windows 7. Any feedback from the UWIN user base would be gratefully appreciated. Many thanks, Richard.
