Polycom RMX 2000 – Reset to Factory Default

RMX 2000 factory default

Resetting a Polycom RMX 2000 to factory defaults isn’t difficult, but it was quite a challenge figuring out the finer details of the process. For some reason, there isn’t a whole lot of easily available information on the Internet. In our particular case, we needed to reset the LAN settings (IP Address, gateway, subnet mask), because we couldn’t remember what they were. Instead of just resetting the LAN settings, we figured we’d just reset the unit to the factory defaults. Our RMX 2000 was installed at a remote site as…

Windows Server 2012 R2 Won’t Show Up In WSUS

wsus

We had a problem whereby new Windows Server 2012 R2 servers won’t show up in WSUS, which by the way is on a disconnected network. The issue had to do with the deployment of a VMware OVA template for new Windows Server 2012 R2 virtual machines. What we discovered was the SusClientId registry entry was the same for each system. Therefore, all virtual machines created from this template shared the same authorization ID. This caused a situation whereby each new server would overwrite the other, such that the last server…

Java Deployment Configuration and Properties

Java deployment has change with version 8, and for us, it changed how we deployed it to all our workstations. We operate 100+ Windows Clients and Servers on a classified closed network. By closed network, I mean it is not connected to the Internet and has point-to-point WAN connectivity to remote sites which first must pass through a TACLANE type-1 encryption device. This creates some problems when it comes to 3-party Java code and signing. Java version 8 is locked down quite a bit more as compared to previous versions….

There are no more endpoints available …

After setting up a new Windows Server 2012 R2 x64 bit server as a printer server, I ran into a problem: There are no more endpoints available for the endpoint mapper. I couldn’t share any of the printers in the Printer Management interface. The solution (in my case) was quite simple, but not obvious, because the error message mentioned nothing related to printers. Our server is set up on a closed network (classified) that is not connected to the Internet or any other networks. Lots of GPOs are applied, which…

Why I Have a Land-line Phone Again

Years ago, I struggled with the idea of canceling my land-line phone and relying solely on my cell phone. The main reason for doing so was cost savings. The land-line phone was costing me somewhere around $40 a month after taxes and all the options. I didn’t see any reason to keep paying for it when my cell phone offered far more features and it was mobile. After much debate, I ended up going through with it, but years later I found myself in the same debate ultimately deciding to…

Polycom HDX People+Content Poor Call Quality

We ran into an issue where the Polycom HDX endpoints degraded with poor call quality. When various endpoints connected to the RMX 2000 bridge and one of the participants pushed content via People+Content, everything seemed OK. However, once the token holder stopped pushing content, many of the participants’ call rates (not all, though) dropped considerably, in most cases by half. As an example, an endpoint that initiated a call request at 1024 Kbps dropped to 512 Kbps. This was enough that the older HDX 4000 and 8000 Model A and…

Slow File Transfers Between Windows 7 and Server 2003

As my organization started to upgrade our domain-joined workstations from Windows XP to Windows 7, we ran into an issue with the clients browsing via DFS (Distributed File System) and file transfer speeds both over the LAN and the WAN. As the users explored the DFS tree, the navigation was extremely slow, sometimes in excess of 20 seconds drilling down just one directory level. Likewise, the file transfers were also very slow between the Windows 7 clients and the back-end Windows 2003 servers. The users were not happy. To make…
