Is there a limit to the PATH variable to about 1000 characters?

Env. Windows NT 4.0 Workstation SP6a

Hello,

I have a temporary need of setting a lot of different search path in the PATH environment variable, but I seem to have hit a limit of about 1000 characters... I have not found any reference in Microsoft Support about that there should be such a limit (I know that MSDOS have a limit of 128 characters for the PATH environment variable), so what I wonder is:

Is there such a limit built in to Windows NT?
and
Is there a way of changing that limit, if any?

Regards,
/Stefan

I would try seeing if you can map local drives

ie map x: to c:\cc\ass\sss\asdasda

then use x:\ in your path search.

I hope this helps !

Hmmmm... yes, so far I have tried SysExpert's solution, but I am still having some problems with NT services, which cannot create such drive mappings on system level (as far as I know, anyway)... the search path must be constructed among the system variables, since the DLL's are used both by NT services and the currently logged on user...

I will try mikelima's suggestion, and see if that works also for NT services... if it does, then it would also be a better solution, since there would not be any confusion among the programs (including the debugger) about where the DLL's are located...

But still I would like to know if there is any official report about that there is a limit of about 1K in the search path, since I have not found anything myself in the Mocrosoft Knowledge Base - only a 128 character limit in the old MSDOS...
