Line 165, Column 4: document type does not allow element "HR" here; missing one of "MAP", "IFRAME", "BUTTON" start-tag

<hr>

The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

The problem occurred because I had placed <hr> between <pre> and </pre> tags. I had something like the following:

<pre>
This is some text
<hr>
This is some more text
</pre>

I eliminated the error by placing a end pre tag after the first block of text and a begin pre tag before the second block of text.

<pre>
This is some text
</pre>
<hr>
<pre>
This is some more text
</pre>

When I tried pinging the internal email server, mail.example.com, from her system, instead of its internal address, 192.168.0.25, being used, I saw the external address for the firewall was being used. I checked her /windows/system32/drivers/etc/hosts file first. I didn't see any entry for mail.example.com there. Nor did I see the address cached on her system when I entered the command ipconfig /displaydns | find /i "mail.example.com" at a command prompt. So I used a sniffer to observe the network traffic from/to her system. I saw that her system was querying the DNS server configured as the secondary name server for her system, which was an external DNS server provided by her Internet Service Provider (ISP) rather than the internal name server on her LAN.

I tried ipconfig /flushdns, but that made no difference. Her system continued to query the secondary name server and didn't seem to ever cache the address for mail.example.com. When I tried ipconfig /registerdns, the system then queried the primary DNS server again.

The /registerdns argument to the ipconfig command "refreshes all DHCP leases and re-registers DNS names." The system had a static IP address, so the "re-registers DNS names" function of the command must have fixed the problem.

When she tried sending her email message again, though, it was rejected by the internal mail server. I had her restart her email client, Microsoft Outlook, and that resolved the problem. Apparently, Outlook also maintains its own cached information for the mail server it uses. I still didn't see the internal mail server's address cached when I issued an ipconfig /displaydns command, though.

The long term solution, though, to prevent the problem recurring would be to set up another internal DNS server to use as the secondary DNS server.

The syntax for the DATEDIF function is as follows:

=DATEDIF(Date1, Date2, Interval)

Where:

Date1 is the first date,
Date2 is the second date,
Interval is the interval type to return.

If Date1 is later than Date2, DATEDIF will return a #NUM! error. If either Date1 or Date2 is not a valid date, DATEDIF will return a #VALUE error.
The Interval value should be one of the following:

If Interval is not one of the items listed in above, DATEDIF will return a #NUM error.

I was unable to backup a disk drive to an external drive attached to a system via a USB connection using the NTBackup program. The backup failed once the backup file reached 4 GB in size, which is the maximum size for the FAT32 file system, which was the file system on the Western Digital My Book USB external drive when I purchased it. So I decided to change the file system to NTFS by reformatting the drive. But I received an error message when I tried to convert the file system.

C:\>format f: /fs:ntfs
NTFS file system is not supported on this device optimized for removal.
To change the way this device is optimized, select the Policies tab in
the device's property sheet.

To change the file system, I right-clicked on the drive under My Computer, then chose Properties.

I then clicked on the Hardware tab and selected the drive.

I then clicked on the Properties button and then the Policies tab. I changed the setting from "Optimize for quick removal" to "Optimize for performance". The "optimize for quick removal" setting disables write caching on the disk and in Windows, so you can disconnect the device without using the Safe Removal icon. The "optimize for performance" setting enables write caching in Windows to improve disk performance. When you choose this option, to disconnect the device from the computer, you should click the "Safely Remove Hardware" icon in the taskbar notification area."

I then clicked on the OK button. I clicked on a second OK button to close the window.

I was then able to reformat the drive from the FAT32 file system to the NTFS file system.

C:\>format f: /fs:ntfs
The type of the file system is FAT32.
The new file system is NTFS.

The HKO_Downloader.exe file downloads the actual software needed to participate in Hello Kitty Online, which is a site run by Aeria Games. I concluded that they may have licensed a downloading program that some others may use for nefarious purposes, but I didn't see sufficient reason to be concerned in this case and told her she could download the software and participate in the beta testing.
