asp.net - File.OpenRead access using UNC path. Impersonation not working? -

-

is there reason impersonation not seem work unc path using file.openread()? i'm utilizing codeproject's impersonation utility:

i have user rights share i'm passing openread().

this code , it's not accessing file:

try {     bool canimp = imp.impersonatevaliduser(impuser, domain, imppwd);      filestream fs = file.openread(filepath);     logger.debug("file stream opened...");     byte[] b = new byte[fs.length];     fs.read(b, 0, b.length);     fs.close();      // code continued

turns out using ip address in impersonation domain, rather friendly domain name. once used friendly domain name, impersonation worked.
