I have a windows server 2003 R2 instance running in a hyper-v instance on windows 8. I have setup an internal switch that uses internet connection sharing to get out to the internet. It works fine except for when I try to do windows update on the server 2003 instance it disconnects my remote desktop session to the windows 8 hyper-v host. When I reconnect it says windows update failed.
I have a client on PC. I have a server on PC. The client and server are connected via a router with firmware based on Linux OS.
The client sends a packet to the server and receive a response. The router must intercept the packets and modify it.
I'm using a VPN connection to a server (using OpenVPN). When I try to access some website through that VPN, I get a connection reset.
After some investigation, I found it is my VPN server who sent those RST packet.
After my server receive several packets, it sends RST packets to the website, cause connection reset.
I would like to know why my server will do this.
I have a problem seen on Windows Server 2008 running IIS 7. I have seen a packet trace where the server stops responding to SYN from clients. However, it will respond to intermediate SYNs i.e
Say Client A sends SYN 1 at time t1.
Server will not respond
Client A now sends SYN 2 for a *different* connection at time t2 (t2 > t1)
Server responds.
Client A retransmits SYN 1 .
I am running three VMs connected over a virtual switch. I configured the vSwitch to forward all traffic from the server VM to both output ports where the other two VMs are connected. Thus the server VM sends traffic to two others. I ran wireshark on all devices and observed that one of the VMs is dropping some TCP packets. So, the number of packets received on the two VMs are not same.
We have a server with a MS-Access Front End that is used as the shell of an RDP connection instead of explorer.exe:
alternate shell:s:"D:\Program Files\Microsoft Office\OFFICE11\MSACCESS.EXE" "C:\databases\%username%\frontend.mde" /wrkgrp "C:\databases\Secured.mdw"
My users run Windows XP and Windows 7.
The RDP server they connect to runs Windows Sever 2003 Enterprise Edition SP2.
And our DC
Summary: how do I create an RDC connection from a Windows 2008 server to another server?
Our client will only allow us to connect to their server via a static IP address (which is fair enough), but unfortunately as we're a very small company we don't have one in the office.
As a work around, we had the connection working through our old Windows 2003 server (dynamic-cloud from 1and1). ..
I'm not really into systems administration, but I was called to set up this Windows 2003 Server. I put it in a VirtualBox virtual machine on the (real) Ubuntu Server.
Firewall for a virtual dedicated server.
I was looking into how to prevent a FIN scan and it got me thinking about the consequences.
A lot of people are using this rule:
-p tcp --tcp-flags FIN,SYN,RST,PSH,ACK,URG FIN -j DROP
So when someone sends me a packet with a FIN = 1 , I'm unable to send FIN/ACK back.
It seems unlikely but does that mean my established connection won't be stopped ?
