Will eBLVD work on hosts with mirrored or imaged hard drives?

Our licensing paradigm does not support starting eBLVD host software that was created from a mirrored or imaged drive. If you have done this, contact us for instructions on how to replace the mirrored license with a new one.

How do I replace / switch a Host PC license to a new or different PC?

To transfer or replace a Host PC license, log in to your eBLVD account, access the Host PCs page, place a checkmark in the box to the left of the Host PC(s) to be deleted, and click the "Delete Checked" link above the list. Alternatively, you can uninstall the software from the OLD PC by clicking START -> All Programs -> eBLVD -> Uninstall Software.

Next, while at the NEW PC you'll be setting up, click the "Set Up This PC" link on the top-left side of the Host PCs page to invoke the Installation Wizard.

Can I change the port that my eBLVD software uses?

Yes. You can configure the port that eBLVD uses from the Advanced Tab of the eBlvd Options, located in the Control Panel of the HOST PC. To minimize connectivity problems over the Internet, we recommend running eBLVD over port 443. Note: If eBLVD is running on a Windows 2000, 2003, or 2008 Server with Internet Information Services (IIS), web-based email server; or other web publishing applications, we then recommend changing this port to another, such as 444 to avoid conflicts.

Can I use eBLVD behind a firewall or proxy?

In almost all cases, yes.

When you start a session, eBLVD attempts to connect to our servers over TCP/IP. In rare instances, firewall configurations will disallow the transmission of Secure Sockets Layer (SSL) packets. This will prevent any machine behind this type of firewall from viewing an eBLVD session.

We're constantly improving our ability to connect immediately and reliably through firewalls and HTTP proxy servers, so if you encounter a problem connecting with your network configuration, please see our firewall and security documentation in our document library.

Can I use eBLVD behind a Network Address Translation (NAT) router or firewall ?

Yes. eBLVD has been tested to work reliably through NAT routers and firewalls.

Can participants connect over dial-up?

Yes. eBLVD works over high- and low-bandwidth network connections. Anyone using a 56.6 kbps or greater modem connection can access the eBLVD service.

Since dial-up data speeds are slower than DSL, broadband or T1 speeds, your session may experience greater latency, i.e., there will be a time lag between the HOST and the viewer.

Could someone intercept and 'view' my eBLVD session ?

Think of eBLVD as you think of accessing secure 128-bit SSL web pages. A sophisticated hacker could intercept your web session but would only see encrypted data. The hacker would need to decode each individual stream of data and reassemble it to be able to view the data. This is virtually impossible.

Do you support dynamic IP addresssing?

Yes, eBLVD works with PCs that have dynamicallly assigned IP addresses.

Do you support Mac/Unix platforms?

Apple Macintosh computers / operating systems, Unix and/or Linux operating systems are currently not supported. However, some Macintosh users have successfully connected to eBLVD Online Meetings from their Macintosh system while using a Windows emulator program. If you're interested in learning more about this subject, please visit http://www.macwindows.com.

Does eBLVD work on systems with multiple monitor systems?

Yes, eBLVD works with Windows Vista or XP's DualView feature (eBLVD sends the "Primary" monitor).

Does the eBLVD icon sitting in my system tray (near the clock) slow down my PC?

Nope. eBLVD only uses processing power during a session.

How big is the remote client (viewer) applet ?

About 350KB, which takes just a few seconds to download over a broadband connection. Once downloaded, eBLVD begins receiving a view of the remote Host PC.

How can I improve eBLVD's performance / refresh rate?

eBLVD's speed depends upon several factors: bandwidth, screen resolution, screen content and network infrastructure.

Bandwidth – eBLVD senses changes in your screen appearance, compresses the information and sends it to a eBLVD server, which relays the data to each of your participants.

Consumer DSL and cable modems have fast download speeds (768 to 1500 kbit/s), but many service providers limit uplink speed to about 100 kbit/s, which can slow eBLVD.

Screen resolution – eBLVD sends your entire screen, so reducing its resolution can improve performance. A complete 800x600 screen can be sent about 2.7 times faster than 1280x1024.

Screen content – eBLVD sends text and lines quickly. Photos and shaded graphics are sent less efficiently and take longer to transmit.

Network Infrastructure – You may want to ask your network administrator to add a simple, secure rule to your company's firewall policy so eBLVD can run at peak efficiency.

How do I configure your software to get through our proxy server?

Depending on whether you're running the eBLVD Host or Client software (the Client software is used to connect to a PC running the Host software), you can set up our remote control products to work with your proxy server.

If you're at the Host PC:

Open eBLVD Options from the 'e' System Tray icon menu.
Access the "Advanced" tab
Remove the checkmark from the "Automatically detect settings" option & click the "Manual configure" button.

If you're using the eBLVD Client software:

Click the "Details" button on the eBLVD Client connection screen
Access the Proxy Settings tab
Remove the checkmark from the "Automatically detect settings" option & click the "Configure Proxy..." button.

How do I remove eBLVD from my computer?

To uninstall the eBLVD software from your computer:

Click on the Windows Start button
Select "All Programs"
Select "eBLVD"
Choose "Uninstall software" from the menu.

You can also uninstall the software by selecting "Uninstall" from the host icon menu, or through the Windows 'Add/Remove Programs' feature.

How do I upgrade to the newest version of the software?

While the Host software is running, right click on the 'e' icon in the system tray. Select the 'Check for Updates' option from the pop-up menu, and the most recent version of the software will be automatically downloaded and installed.

You can also update the software by clicking on the 'Windows Start button':

Select 'All Programs' -> 'eBLVD' -> 'Software Updates'

How secure is eBLVD?

Secure connections (often called SSL, or Secure Sockets Layer) is the industry standard in Web security. It is used primarily for transmitting sensitive information over the Internet. When you have a secure connection between your browser and another computer, it is impossible for someone to access the data that you send across that connection. eBLVD software products encrypt all outgoing packets from the client, encrypt all display packets being returned to the client from the host, and encrypt all file, clipboard, and chat transfer packets. This method of encryption secures sensitive data as it travels over the Internet. The specific technology used is end-to-end 128-bit SSL encryption.

We keep the actual physical hardware used to provide the service in world class, tightly-protected, 24x7 managed, professionally-run data centers with redundant servers, network devices, and bandwidth providers. Plus, eBLVD is a Verisign Secure Site and a certified licensee of the Trustwave Payment Card Industry (PCI) Data Security Standard Program supported by all the credit card associations.

What if the client and Host PCs have different sized monitors or resolutions?

The eBLVD Client browser (the window that displays the Host PC's desktop) can automatically match the resolution of the Host PC. To perform this function, have the person connecting to the Host PC click the "Scale Desktop" button on the eBLVD Client browser toolbar.

What is a firewall?

A firewall is a security mechanism that keeps your network safe from intruders. It may protect a network while users connect to the Internet, or it may separate a company's public web server from its internal network. Firewalls are also used to keep segments of networks secure. When properly set up, eBLVD services are compatible with most firewalls.

What is a proxy?

A proxy server is an intermediary server used by some Internet services to improve security or network performance. Most eBLVD services will work through a proxy server if properly configured.

Why has the eBLVD icon next to my clock disappeared?

Windows XP often tries to hide icons. To make the eBLVD icon next to the clock always visible:

Click Start > All Programs > eBLVD > eBLVD Options then click "Start Host Software" to make sure eBLVD is running.

Right-click a blank spot on the Windows Task Bar and choose Properties. The Taskbar and Start Menu Properties dialog box opens.

Click Customize... in the lower right corner, which opens another window.

Locate the line with the eBLVD "e" icon, click its entry in the Behavior column, choose Always show and click OK.

One of the computers on my account has gone into Hibernate or Sleep mode.

To prevent your computer from hibernating and therefore interfering with your eBLVD session follow these steps:

1. Open the Windows Control Panel
2. Open the Power Options properties
3. Change the options for "System standby" and "System hibernates" to "Never"
4. Click on "Apply"
