I have a SMB share on a CentOS server. Windows 7 based clients connect to the server via OpenVPN. Then net use is used to init the share.

On some clients (not all) I am experiencing very long connection times (from 15 to 40 seconds, with rare terrible peaks of 2 minutes). Once the client is connected, download times of shared files are OK.

I examined network traffic with Wireshark and noticed that those delays are caused by a lot of time that passes between my net use command and actual "Negotiate Protocol Request" packet departure from my ip. After that, the connection is estabilished fast. To me, it looks like net use just sleeps for a random amount of time before acting, with no known reason.

This happens on various PCs, even with freshly installed Win7 OS.

  • Sounds like a DNS issue (possibly with AD complications).

  • I'm using the ip address of the server, so DNS shouldn't be involved, right? I do see loads of NetBios packets on the VPN interface but they don't seem to fill the bandwidth
