I wanted to underscore what one other poster mentioned... If you are actively running UniData on two different servers, the only safe way to access a UniData file on the 'other' server is via NFA. The reason for this is that all file access controls (group locks and record locks) are maintained in local shared memory (Windows memory mapped files). You can likely make Windows shares work, but you risk corrupting your data files with concurrent access from two different servers. A udt process on Server A does not have any knowledge of a udt process on Server B accessing the same file on Server A (or vice versa).

Thanks for your help people. I enquired about the licence for NFA and at 2 grand per server I think I'll work around it somehow.

This works for me: 001: F 002: \\SERVERNAME\UNIDATA\Datadir\FileName 003: \\SERVERNAME\UNIDATA\DictDir\D_FileName Both are ud 7.1.6 one on XP and one on win 2003 (remote) and the D:\unidata dir is shared as unidata.

In an application on server "A" I want to access data held in an application on server "B" I have tried the voc entry in the application on serverA 001: F 002: \\serverB\unidata\filename <file:///\\serverB\unidata\filename> 003: \\serverB\unidata\D_filename <file:///\\serverB\unidata\D_filename> I have also tried replacing "serverB" in the above with the IP address But I get the error "open file error no such file." Anyone know what I should be doing?
