File Sharing / Complete Lockup Under a class of children accessing the same file!!!
Okay ... i'm at my whits end so lets hope something knows a simple "i know whats wrong".
So i have a Windows Server 2012 DC which is serving User Home DIRs and Share Files.
Dell R610 with a DAS MD1220 connected.
So i have a standard share which is all privileged nicely.
We have \\server\ShareFiles (the share path) mapped to K:\ which contains all our lovely shares that fill we useless detritus over the years.
== Here is the problem ==
Teacher A places a file in K:\Students\4F\editandreturndocument.docx
Teacher A asks class to "Open the File" and "Save As" to their own workspace, fill it out and return it.
Class of (22) children click the file (or any file shared for that matter) and every station cant (it crashes waiting for the file to open) a file just previously accessible is now "inaccessible".
It is obviously caused by some kind of limit. But 2012 server standard does not seem to have one, and yes it is licensed. Unlimited connections allow to the share, unlimited users allowed.
It is certainly not confined to simply share files either \\server\userhomes\students\ is also effected. So if you say login as a group login say "year1" (babys not so good with the logins :)) then they all take a solid 5 minutes to login over the previous 30 seconds.
Offline Files are OFF, Folder Redirection On.
This is driving me up the wall. If you know of anything that may cause this, please post, at this stage i will try anything. My Microsoft Certs do NOTHING! Proving useless!!!! Respectfully requesting out geeking :D
