iShareDisk is required to use the following ports at first: 67 (DHCP), 69 (TFTP), 3260 (iSCSI) and 3265 (admin port). If you already installed firewall or anti-virus software on server, please ensure these ports are open.

You should save the image as follows:
1. Right-click the target client PC at the User List of the server. Then click "Superuser" command and boot up corresponding client PC.
2. Install the software or update game, shut down the client PC. Then go back to the server, click "Superuser" command. The system will remind you of saving wirteback data.

Please go to official website and download the latest version. Stop all the services before installation.

The ssd cache is a lower-level cache of memory cache and cache data stored in the ssd disk. When a client requests to read the data does not exist in the memory cache will start ssd cache to find, and then find the actual data. Readed data then be saved in ssd disk have been ready for the next read. After ssd filled, back data cache will overwrite the existing cache data, but the the ssd cache file size would not be changed, just the content would.

Yes, you can combine these two together. However, in Windows 2008, because the super cache is in error after being used by write-back disk, please shutdown super cache function on the disk.

Copy the set file from the original server. Please note that if some  disks are different in paths on two servers, you need to set them again.

Please edit client and set "Use Compatible PXE to Boot Up". This would be slower, but not affect the speed after entering Windows. (Or later) network card upgrade rom.

1. Error version of the network card driver or scrolling blue screen is not installed yet.
2. The client PC is installed with anti-virus software, such as nod32, etc.
3. No client PC is installed. Please install before upload.
4. If the client PC is installed with ISD, please re-start the PC before uploading image.

It is recommended to ensure sufficient space of virtual memory for diskless client PC. The larger the virtual memory is, the better the result is. For example, minimum is 4096 and maximum is 4096.

1. System differences. Reading traffics from different OS versions might be very different.
2. System Optimization: it is necessary to optimize the system, for example, shutting down system pre-reading, etc.

This may occur due to the following reasons:
1.  Space of the  disk on the server is not enough.
2.  Internet problem, internet unconnected, network card does not support to send large data package.

It may be caused by two reasons in general:
1. IP within the LAN conflicts with the one assigned by DHCP; or
2. The write-back disk is full.

1. You did not designate image file to boot up, or the image package is damaged; or
2. The start IP can not be loaded after booting up;
3. Interfered by other DHCP, such as router or switch.
4. The BIOS on the main-board needs to be upgraded.
