I have scripted Quota.bat to implement a shared folder quota system on a 'server'.
For each 'server' that you implement, Quota.bat will detect if the shared folder(s) on the 'server' have exceeded your limit(s), and if so, for each shared folder whose limit is exceeded, Quota.bat will prevent additional writes to the share, and send an email to as many 'share managers' as you desire.
To implement Quota.bat on a 'server':
1. Define three (3) files in the same folder as Quota.bat:
Quota_wait.txt contains a single entry, the number of seconds to wait between each quota checking cycle. If you type 60, Quota.bat would wait 1 minute. If you type 300, Quota.bat would wait 5 minutes. Quota_msgtxt.txt contains the fixed text of a message that will be send to each 'share manager' when a quota is exceeded. It can be as simple as: Quota.bat detected that the subject limit has been exceeded. since the message subject contains the computer name, local share folder name, quota limit that you set, and the size detected. Quota_limit each line contains the configuration parameters for a share on this 'server': Folder Path,Limit,RMTSHARE command,email addresses where: Folder Path is the local path to the shared folder, like C:\Users. Limit is the maximum number of megabytes allowed. RmtSHARE command is the RMTShare command that changes the share permissions to Read. If C:\Folder\Accounting is shared as \\ComputerName\ShareName and the domain groups "Accountants" and "Accounts Payable" in the JSIINC.COM domain had Full Control or Change permission, use: rmtshare \\ComputerName\ShareName /GRANT "JSIINC\Accountants":R /GRANT "JSIINC\Accounts Payables":R email addresses is the comma separated list of email addresses that should be notified when the quota is exceeded, like: Jerry@jsiinc.com,HelpDesk@jsiinc.com,AcctMgrs@jsiinc.com 2. Start Quota.bat. I use a Scheduled Task that is configured to run Quota.bat when the computer starts.NOTE: When a quota is exceeded, after correcting the situation, delete the Folder Path line from the Quota_Exceeded.txt file that is created in the same folder as Quota.bat, and reset the share permissions to allow writing.
