Issue Does the STR-250 work on Micro Regulators (MR)? Environment I/NET Seven STR-250, I/STAT, M/STAT I/SITE Controller and Micro Regulators (MR) Cause The STR-250 Wall Module is the replacement for the commonly referred to I/STAT sensor, still referenced in I/NET documentation.  The I/STAT is no longer available.  Resolution The STR-250 sensor is the replacement for the I/NET I/STAT, so installation and configuration for the STR-250 is as per this I/STAT. There are two documents that will provide assistance with this TCON126 and TCON299 (Chapter 21). The STR-250 full functionality must be installed on the I/STAT port of any I/NET device and configured as detailed in the above documents. Only one I/STAT port exists per MR. The M/STAT is still available and is used as the hardware tool for configuring the controller settings on all supported I/STAT devices, such as, all Micro Regulators (MR) variants, I/Site LAN Controller (Model 7728) and Xenta 102-AX.

Issue License settings for different users on Win2008 Server R2 differs from previous versions OS. The user that installs the license system (either with TAC  Vista or as a standalone) will make the initial license configuration in the .Default user in the registry. Next time a new user (that has never logged on to this server before) logs on to the PC, the default license settings are copied to this users profile. Then the user who has installed the license system logs in to the server, and changes the license settings. Now, when the second user logs in again, the license settings are the same as they were in the beginning. It seems that these settings are not stored in the general system settings, but actually in the domain users profile that are fetched upon login. So, all users that have logged in with wrong or not updated license settings, will have to login again and change their settings. Environment Windows 2008 Server R2 TAC Vista Cause Unable to access licenses when logging in with other account than used when changing license path. Resolution If changes are done to the license path ,every user has to manually change their settings to get the system to work. Or, a batch file or similar has to be run upon login to change settings in question.
