Hi...all I have a stand-alone windows server 2003, running active directory, file services, IIS for citrix and DHCP/DNS. Description: The server's configuration parameter "irpstacksize" is too small for the server to use a local device. Please increase the value of this parameter. Please help as I have not encountered this error before and couldn't really find a lot of info on it. I have tried creating a registry entry with a value larger than the default size, but I am still getting the above error. I have a VPN firewall and I haven't had problems until recently been running for a year and a half just fine. I also get another error that's says access denied when I try to map a network drive from the server. Not sure if this error is related to the original error message about the irpstact size being too small. ThanksBest Regards, Joshua Glass Systems Enginer
