Slow LAN Issues

[ReverentCreature]

I have staff here struggling to load web pages on their computers. The busy ring spins in the tab even when a page seems okay. Other pages take ages to load.

 

Thought it was a chrome issue but its affecting all browsers and multiple computers.

PINGS to the Internet are okay, SpeedTest.net shows a normal connection.

I cannot see much in the windows event logs to suggest any issues. Login speeds and drive mappings seem okay.

 

I'm at a loss now what to do next? Can anyone help?

 

I have spotted on my wireless computer these events in the logs:

DNS 1014 and DNS 8015.

But I don't see these on the wired computers so I'm not sure if its a related issue.

How many internal DNS servers do you have?

What did you change before this happened? Have any servers had any problems?

WHat DNS servers are you using on the clients?

How are those DNS servers configured?

Are you using a proxy / filter system?

 

Wildcard question: are you redirecting AppData?

I was experiencing some slowness today while looking at a member of staffs laptop and on my computer clicking on links through Outlook which then did the dots going across the screen loading before eventually going to the website. Same as you all Speedtest's and dns lookups seem fine.

 

I was in meetings all the rest of the day so not sure if still happening. Is yours still an issue?

Hi I think it could be the filtering system. Medway Council are reporting slow internet but fast speedtest results. They believe there is an issue with their filtering system.

Ill check the DNS. We have two domains here. Admin and Curriculum. I want to crap the admin soon creating a SIMS member server on the curriculum network.
