Take the tour ×  We have an application that makes request to a
UNC path for files and serves them via IIS.  How many concurrent
connections can a process on Windows 2008 r2 make to a UNC file
share?  Are there any specific limitations on this, or is it
purely a based on physical resource constraints (and number of
available ports for TCP/IP connections).  share|improve this

Assuming your UNC file share is also a Windows server, then the
max is really only limited by CAL licenses owned (but not
actually set anywhere but on paper).  Since this is asking
concurrent connections, you can check it here (on the server
with the share):   Look at the share and there is a REG_MULTI_SZ
that should say "MaxUses"  the default is some crazy high number
like 4294967295 (65536 times 65536 minus 1) based on ports like
you say (no it's not a reference to Excel :) )  share|improve
