Joker Mail Forwarding
The domain registrar, Joker.com
to have email addressed to someone at a domain registered with them forwarded
to an email account at another domain. E.g., one could forward email
addressed to email@example.com to firstname.lastname@example.org. Joker.com
imposes the following limits for that service:
- 40 mail addresses per domain
- 10486kB as the maximum size of a single mail
- 200 mails per day per address
Joker.com provides the option of filtering spam. Hopefully, email rejected
as spam doesn't count towards the 200 email messages per day limit.
The service might not be suitable for someone who receives large attachments
to messages, because of the 10 MB limit on the size of a message.

HR Tag Within Pre Tag
When I checked a webpage for HTML errors using the
W3Creg; Markup Validation
, I saw errors such as the following reported:
Line 165, Column 4:
document type does not allow element "HR" here; missing one of
"MAP", "IFRAME", "BUTTON" start-tag
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
I had something like the following:

Windows XP System Not Using Primary DNS
After a user rebooted her system, email she sent to an internal POP3 email
server was being rejected. When I checked the email server's log file, I found
that it was rejecting the email because it saw the email coming from the outside
address of the firewall. It saw the "to" address of the email message she was
trying to send as one that was not destined for an account on the email server
and rejected it with a "relaying denied" message. The email server was
configured to allow relaying from the IP address of her PC, but since it
saw the email coming through the external firewall, it rejected it.
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
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.
/registerdns argument to the
"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
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

Creating a CD Image with ISO Recorder
I needed the capability to create an

by the following steps:
- Click on the Start button.
- Select Computer.
- Right-click on the CD/DVD drive and select "Create image from CD/DVD".
- Select the location and file name for the ISO file you wish to
- Click on the Next button.
- Click on the Finish button to exit ISO Recorder.
ISO Recorder also then allowed me to right-click on the ISO file and choose
"Copy image to CD/DVD" to create another copy of the CD.

File System not Supported on This Device Optimized for Removal
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
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.

Hello Kitty Online - Trojan.Win32.Generic!BT
A family member got an offer to become a beta tester for
Hello Kitty Online
today. The email message she received provided a link to download
a setup program
. After she downloaded
the file, I had her submit it to Virustotal
, a site that checks files for malware with multiple antivirus programs.
Virustotal analysis of the file
showed 2 of the 41 programs it used
to check the file reporting a potential issue with the file. Note: someone
else had uploaded a file named

because that file had an identical

concluded that they may have licensed a downloading program that some others

concerned in this case and told her she could download the software and
participate in the beta testing.
