如何使用Add-DnsServerResourceRecord为单个TXT DNS资源记录添加多段独立DescriptiveText内容

Let's fix this directly: the correct way to create a single TXT record with multiple quoted segments is to pass a string array to the -DescriptiveText parameter, but you need to format the array correctly so PowerShell doesn't misparse it.

Working Command #

Use an explicit array with @() or store the array in a variable first—both methods will create the single multi-segment TXT record you need:

Option 1: Direct Array Passing

Add-DNSServerResourceRecord -DescriptiveText @("a", "b", "c", "d") -Name "identifier" -Txt -ZoneName $ZONE -ZoneScope $ZONE_SCOPE -TimeToLive 0:1:0:0

Option 2: Array in Variable

$txtSegments = @("a", "b", "c", "d")
Add-DNSServerResourceRecord -DescriptiveText $txtSegments -Name "identifier" -Txt -ZoneName $ZONE -ZoneScope $ZONE_SCOPE -TimeToLive 0:1:0:0

Why Your Previous Attempts Failed #

• Unquoted array ("a","b","c","d"): PowerShell interprets "b" as the next positional parameter instead of part of -DescriptiveText's value, causing the error. Wrapping with @() explicitly tells PowerShell this is a single array argument for the parameter.
• Manual quote formatting: Adding quotes to your string (e.g., "\"a\" \"b\"") will only include those quotes as literal text in the TXT segment, not create separate quoted segments.
• Individual command calls: Each call creates a separate TXT record, which isn't what you need—DNS allows multiple segments within a single TXT record, not multiple distinct records.

Verify the Result #

After running the correct command, query the record to confirm it works as expected:

Get-DnsServerResourceRecord -Name "identifier" -ZoneName $ZONE -ZoneScope $ZONE_SCOPE -RRType Txt

You'll see the RecordData.DescriptiveText property is an array, and standard DNS queries will return it as TXT "a" "b" "c" "d" exactly as you wanted.
