Internet Explorer Proxy Settings May Disappear

When you add or modify the proxy settings for Microsoft Internet Explorer and the new settings are accepted, the new settings may be missing and the boxes may be blank when you view the proxy settings.

This behavior can occur for either of the following reasons:

• If you use a backslash (\) instead of a slash mark (/) when you type a Uniform Resource Locator (URL).
  For example, you type http:\\servername instead of http://servername.
• If you use a slash mark (/) instead of a backslash (\) when you type a universal naming convention (UNC) path.
  For example, you type //servername instead of \\servername.

To resolve this issue, use the correct addressing scheme:

• For URLs, use a slash mark (/). For example:
  http://servername
• For UNCs, use a back slash (\). For example:
  \\servername

To locate the proxy settings for Internet Explorer:

1. Click Start, point to Settings, click Control Panel, and then double-click Internet Settings (or click Internet Options on the Tools menu in Internet Explorer).
2. On the Connections tab, choose the dial-up settings that you want to configure, and then click Settings.
3. In the Proxy Server area, click Advanced.
