I have installed client networking on NT4.0 workstation many times and SQL Explorer works fine. I recently installed it on an NT4.0 Server machine and it won't start. i get the following error: 'error parsing file to execute: (wjview)'. Now, on all machines where SQL Explorer works, the file wjview.exe exists directly under the WINNT directory. it doesn't exist under the WINNT directory of the NT Server machine, where SQL Explorer does not work. at first, i thought it was a service pack (patch) issue...since the NT server machine is S.P.5 and all the workstations are S.P.6. i found this to be bad info though, b/c i found an NT workstation machine on my network with S.P.3 and it has the file 'wjview.exe' in it's WINNT directory. so, my only guess now is that the file doesn't exist on NT Server, and thus SQL Explorer will not run under NT Server. btw, i did try just copying the file to the NT Server's WINNT directory, and this results in other similar errors. Does anyone out there have any info/thoughts on this?
