I found there was a rogue computer connected to the network that was causing all of my problems. &nbsp;Someone connected a computer that was configured as a firewall and was running various services... When I disconnected the PC the problems we were having disappeared. &nbsp;Needless to say, I had a pretty heated discussion with the person responsible.

In the middle of last week I started receiving complaints from users that they have been experiencing slow downs and disconnects from the network. &nbsp;Some of the symptoms are sometimes is take a long time to open a file or print from the server, Outlook will disconnect from Exchange and reconnect 10 - 20 seconds later, Iseries Access loses it's connection to the AS400... &nbsp;I believe I am having a problem with my switches (all 3COM 4500) however I cannot pinpoint where the problem is. &nbsp;I have been running a continuous ping to a few clients that have reported problems and they do not appear to be losing connection. &nbsp;<br />

Any help is greatly appreciated.

Intermittent Disconnects on Network

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

Network Operations

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
