a network socket is an entry into a network. it allows transmission of data from one computer to another. engineers create a socket, tell it how to find the other computer, and then tell it to send. to receive data, a socket is created, told which computer to listen to and wait for data to come pouring in.(source: wikipedia) do you have transport rules in place that are used for moderation?  sound like one is in place and isn't properly configured. 
emc > organization configuration > hub transport > transport rules that is where i'd start as well. osi...
so:
1. physical link (maybe check the patch panel and the cabling that's involved in connecting to the computer, maybe swap cables and try a usb to ethernet adapter to rules the nic out.
2. data link - check the switches and switchports on the way. maybe try to use different portts
3. network - most likely not an issue if all the other computers are working fine...
etc.
but this is pretty much it: Your card is ok. There is interference between the router and your computer.  

  

1. The router or the PC may be "hidden" behind a metal cabinet, refrigerator, etc.  

2. Move router higher  

3. Microwave ovens and some cordless phones (not cellphones) that use 2.4GHz will interfere with the 2.4GHz WiFi signal.  

4. Point the router antennas in-line with the direction of the PC.  

5. Move the router closer to the PC. VLANs, trunks and tagging are all related. As you probably know a VLAN defines a broadcast domain, trunks allows vlans to travel from switch to switch and taggings either use the InterSwitch Link (ISL) which is Cisco proprietary or the open standard 802.1q. So to put it a bit more simply a trunk permits different vlans which are tagged to traverse over the link.


A good article describing this is an [introduction to VLANs](http://archive.networknewz.com/networknewz-10-20030725IntroductiontoVLANs.html).


If you are dealing with Cisco switches [understanding knowledge of VTP](http://www.cisco.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080094c52.shtml) is also necessary.


To create a VLAN enter global configuration mode


config t  

vlan 10  

name Sales  

exit


Creates vlan 10 with the name Sales


To assign a port to this VLAN you would create an access port


e.g.


config t  

int fa0/1  

switchport access vlan 10  

switchport mode access  

exit


to assign a range of ports (0 to 5) to vlan 10  

int range fa 0/1 – 5  

switchport access vlan 10  

switchport mode access  

exit


To create a trunk link between two switches requires you set up a trunk port


on the interface


switchport mode trunk


You will need a layer 3 device such as a router or L3 switch (3750) to perform intervlan communications.


The propagation of VLANS from a master switch (VTP server) to client switches requires setting up a VTP domain if you do not want to create VLANS on each individual switch. following cards have been verified

sta… a frequency converter, also known as a frequency changer, is a device that takes incoming power, normally 50 or 60 hz and converts it to 400 hz output power. that's exactly what it is. the ports you use for hdd's and so on. the pcie lanes are shared between them so if you use the m.2 slot, you lose the ports that share the lanes. 

it's only 2 and you still have 4 more :)

love my aorus pro wifi btw. snazzy board that works well and looks good doing it Yes, there are KVM switches that support multiple monitors. do a search for multi-display KVM.


with regard to send print jobs to the printer, the best approach is probably going to be to buy a wireless printer and hook it up on your local network. fwiw the perc4 or perc5 (guess that is what is in the 2950) are lsi manufactured boards. i've had success interfacing the raid arrays with the lsi array manager software. you will need to get the version for that vintage of raid controller. edit: a quick google-fu shows a dell perc4/dc 
is an lsi megaraid 320-2e
